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.
