NFL suspends Antonio Smith for swinging helmet at Richie Incognito

According to Ian Rapoport of the NFL Network,  the NFL has suspended Texans defensive lineman Antonio Smith for the final 2 preseason games and the first week of the regular season for swinging a helmet at Dolphins offensive lineman Richie Incognito during last week’s game.

I think two regular season games would have been more reasonable, but the NFL has ruled.
