Question on a Penalty...

[slippery rock]

NCAA college rules.

A LB blitzes and has a clear shot at the QB. He hits the QB in the chest with his helmit on first contact. Is this a penalty?

The player doesn't seem to be spearing the QB with his helmit, in that, the player doesn't seem to be exaggerating his movement with his head extended forward. It appears to be a normal tackling motion, but first contact is helmit to QB chest.

Thank You in advance.
