12 - 3 forwards, 2 defencemen and a goaltender for each team during non-penalty play.
22 for Ice Hockey
As far as I Know there are 4 players per side.
Ask USA Hockey.
That does not make any sense
This is a rather dumb question since, as in any sport, a player can play as long as his abilities, age, desire, and a team's need for him allow him to do so!!
12 players in total 6 on each side including the goaltenders.
