In all codes of rugby, a player may be temporarily suspended for a period of the match. In rugby union and rugby league, the standard suspension period is 10 minutes (out of an 80-minute game). This is generally referred to as a 'yellow card' as players are generally shown one in a manner similar to association football. Suspended players are said to be sent to the sin bin and is signaled by the referee showing two outstretched hands to the offender (rugby league) or by a yellow card (rugby union). In the Northern Hemisphere it is not uncommon for referees to use both red and yellow cards in rugby league, similar to rugby union.
