NEW YORK (AP) - The NFL will immediately begin suspending players for dangerous and flagrant hits, particularly those involving helmets.
The league's announcement comes one day after its vice president of football operations told The Associated Press such penalties could be forthcoming.
The NFL said such discipline will be in place for this weekend's games.
In the past, players were either fined or ejected for illegal hits.
But after a series of flagrant tackles last weekend, several of which resulted in concussions, the NFL ratcheted up the punishment.
