Unsportsmanlike on an Injured player

[cougar729]

Last night we had a defensive player get his leg tangled up with two offensive players, they were about 5 yards behind where the ball became dead. As he goes down in pain, he takes his helmet off and forcefully throws it towards the pile of players coming off of the ball... We had an unsportmsnalike on him for throwing his helment... Coach said he understood, but as a crew we discussed whether or not we would have had a penalty if he would have taken his helmet off and tossed it to the side or away from other players... any thoughts?
