Olympic fans, prepare to watch hookers in a scrum who hope not to end up in the sin bin.
The lexicon of rugby, and the men's game itself, return to Olympic competition after a 92-year absence. The return in Rio also involves a couple of debuts: It's the first Olympic appearance for women in the sport, and a first for Rugby Sevens. It's a seven-on-seven game. Traditional rugby has 13 or 15 a side.
Sevens is a fast, physical and unpredictable game. Rugby organizers hope an Olympic showing will spread the game's popularity beyond traditional hotbeds like New Zealand, Australia, South Africa and the U.K.
For those who didn't grow up in those countries, rugby knowledge is limited.
Americans might be able to conjure up images similar to football. In rugby, teams move a watermelon-shaped ball toward a goal line, or the try line.
Players move the ball by running with it or passing, although there's no forward passing. Players can also advance the ball by kicking it. And there's tackling, a lot of tackling, but the players don't wear pads or helmets.
During pre-Rio training at the U.S. Olympic Committee's facility in Chula Vista, Calif., U.S. women's team captain Kelly Griffin offered a primer on the game.
"Rugby Sevens especially is like the perfect game for America," she said, "because one, it's fast-paced."
At a U.S. women's practice, three offensive players sprinted toward three defenders. The ball carrier either shoveled an underhand pass to a teammate, or faked the pass and tried to split the defense. It was a high-speed drill and a good example of the game's pace.
Sevens is a lot faster because it's played on the same sized field as traditional rugby but with half the players. The game is much more wide open.
Not only is the action fast, the games are too.
Seven-minute halves. In between, a barely-long-enough-for-a-bathroom-break halftime. In total, a 16-minute game.
Which, actually, is plenty of time, according to U.S. team member Jillion Potter.
"In 30 seconds you can win or lose a game," Potter says. "You can be down with one minute to go, and you need 14 points, and you can turn around and win the game. It's that kind of intensity, that kind of excitement that will draw people in."
So will the hitting. That's another reason Griffin says Rugby Sevens is the perfect game for America. This country loves a good smack to its sports, and rugby lets women fully in on the action.
In post-Title IX America, female athletes get many athletic opportunities. But not often the chance to hit, and be hit, as part of a team game. Richelle Stephens, 20, who plays the position of fly-half for the U.S., says before rugby, she had to seek out contact in other ways.
"In softball, I used to do the collision at home plate," she laughs, adding that she'd do it even if she didn't need to.
"It was so silly, but I liked getting in someone's face."
On this day, Stephens is sporting a rainbow-colored shiner, courtesy of rugby, under her left eye.
Her teammate Potter is in a class of her own when it comes to rugby toughness. She's a cancer survivor and is playing six years after breaking her neck in a match. She admits being hesitant when she first came back from the injury.
"Yeah, there was a little bit of timidness, I think, coming back," Potter says, adding, "but just gradually building back to the tackling technique and the form and establishing confidence again. And then, once you get that a little bit and hit a couple of pads, you hit a couple of people, and then you're like, 'All right, let's play!' "
Potter says the neck injury was a fluke. U.S. women's team athletic trainer Nicole Titmas says most rugby injuries are not as dramatic.
"Ankle sprains, knee sprains, shoulder separations," Titmas says. "We've had some ACL tears, but those numbers are down. We have special training and work on prevention."
Titmas says the quick turnaround in Sevens games helps.
"With it being seven-minute halves, we'll get through a bunch of games and not really have much [in the way of injuries]," she says.
There's always been an assumption rugby is safer than American football, because players aren't tempted to make dangerous hits with no outer protection.
But that's been challenged in recent years, with the intense focus on head injuries in football and all sports.
Hooker in a scrum
Physical, fast, lightning-quick games. There's a lot to "draw people in," as Potter predicts. But a new wave of interest also depends on fans understanding the game. There's a lot of jargon, and there are many technical aspects to digest.
There are positions such as prop and hooker. The latter is a player who hooks the ball with their feet to an open teammate. That happens during a scrum, the classic rugby action where a group from each team locks shoulders and arms in what looks like a big, interconnected huddle. A score is called a try, rugby's version of a touchdown, when the runner crosses the try line and touches down the ball.
That's the briefest of primers. Or, there's Rugby 101 from Jillion Potter:
"Tackle the person with the ball; run when you have it," she laughs. "That's the first thing they teach you."
Potter and her teammates are considered medal contenders in Rio.
The favorites include New Zealand, Australia, Canada and England.
On the men's side, the U.S. actually is the defending Olympic champion — the Americans won the gold medal in 1924, the last time the sport was in the games. It was 15-man-per-side rugby in 1924.
A lot has changed in 92 years, and while the U.S. men, like the women, have a chance at a medal, they're not among the favorites.
The short list includes Fiji, New Zealand, Australia and South Africa.
Competition for the women begins Saturday and wraps up a mere two days later. The men have their three-day tournament right after.
Like everything else with Rugby Sevens, it's fast.
RENEE MONTAGNE, HOST:
And 92 years of missing out on the Olympics, and rugby players are back. The return of rugby in Rio marks the first Olympic appearance for women in that sport. It's also the debut of rugby sevens. It's a seven-on-seven game - half the number of traditional rugby - and sevens is fast. NPR's Tom Goldman reports.
TOM GOLDMAN, BYLINE: I didn't grow up in New Zealand or Australia or England, so my rugby knowledge, like many Americans, is limited. I can conjure up images kind of like football, teams moving a watermelon-shaped ball toward a goal line, tough players tackling without pads or helmets, running with the ball and passing, although no forward passing. On a summer visit I made to the Olympic Training Center in Chula Vista, Calif., U.S. women's team captain Kelly Griffin was patient. She knows my type.
KELLY GRIFFIN: Have you watched any rugby at all?
GOLDMAN: Not much, not much.
GRIFFIN: Well, it's a very - rugby sevens especially is, like, the perfect game for America because, one, it's fast-paced.
UNIDENTIFIED WOMAN #1: My ball, my ball, my ball.
UNIDENTIFIED WOMAN #2: Go, go, go.
GOLDMAN: During this morning practice, offensive players sprint toward defenders. The ball carrier shovels an under-handed pass to a teammate or fakes the pass and tries to split the defense. Sevens is a lot faster because it's played on the same size field as traditional rugby but with half the players. The game's much more wide open. Not only is the action fast, the games are too - seven-minute halves in between a barely-long-enough-for-a-bathroom-break half-time. In total, a 16-minute game, which actually is plenty of time, says U.S. team member Jillion Potter.
JILLION POTTER: You know, you can be down with one minute to go and you need, you know, 14 points or something, and you could turn around and win the game, you know? So it's just that kind of high intensity, that kind of excitement that will draw people in.
GOLDMAN: So will the hitting. That's another reason Kelly Griffin says rugby sevens is the perfect game for America. This country loves a good smack to its sports, and rugby lets women fully in on the action. In post-Title IX America, female athletes get many opportunities but not often the chance to hit and be hit as part of a team game. I asked Richelle Stephens whether that was frustrating in her pre-rugby the life. She plays the fly-half position on the U.S. team.
All that time you were playing those other sports, did you feel an inner beast that you had to let out?
Now, before she answers, I'll note on this day Stephens was sporting a rainbow-colored shiner - courtesy of rugby - under her left eye.
RICHELLE STEPHENS: In softball, I used to do the collision at home plate (laughter).
GOLDMAN: Even if you didn't need to.
STEPHENS: Yeah (laughter). It was so silly, but I liked the, like, I don't know, just getting in someone's face.
GOLDMAN: Jillion Potter is in a class of her own when it comes to rugby toughness. She's a cancer survivor and is playing six years after breaking her neck in a match. She admits being timid when she first came back after the injury.
POTTER: And then kind of once you hit a couple pads, you hit a couple people, and then you're like, all right, let's play.
GOLDMAN: Physical, fast, lightning-quick games - there's a lot to draw people in, as Potter predicts. But a new wave of interest also depends on fans understanding the game.
ANDREW LOCKE: Don't worry about the pad. Just focus on the ball.
UNIDENTIFIED WOMAN #3: Left, left, left, left, left.
GOLDMAN: There are kickoffs. Assistant Coach Andrew Locke leads a kickoff drill at this practice. There are positions such as prop and hooker, a player who hooks the ball with their feet to an open teammate. That happens during a scrum, the classic rugby scene where a group from each team locks shoulders and arms in what looks like a big, interconnected huddle. A score is called a try - rugby's version of a touchdown - where the runner crosses the try line and touches down the ball. That's the briefest of primers, or there's rugby 101 from Jillion Potter.
POTTER: Tackle the person with the ball. Run when you have it (laughter). That's what - the first thing they teach you.
GOLDMAN: The U.S. women are considered medal contenders. The favorites include New Zealand, Australia, Canada. Competition begins the morning after the opening ceremony and wraps up a mere two days later - like everything else with rugby sevens, fast.
