In rugby union sevens, the sending-off period is 2 minutes, which despite being eight minutes shorter, is actually a more severe penalty for two reasons: a) a normal sevens match lasts only 14 minutes instead of the 80 used in 15-man union or 13-man league, meaning that the penalty lasts one seventh (14.3%) as opposed to one eighth (12.5%) of the match, and b) during this time, the offender's team must play without one seventh of their team; this opens up more space than losing one thirteenth or one fifteenth of the side.
