Thursday night's Raiders and 49ers game was all about third string quarterback Nick Mullens. One of the season's more gruesome injuries took place as well.
49ers running back Raheem Mostert suffered a nasty broken forearm. His arm snapped when he put it on the ground after being tripped up by a defender.
Mostert might want to up his calcium intake as he recovers. This is a play that occurs multiple times during every football game. If your arm can't handle it, you either need to strengthen your bones or find another profession.
