FOX Sports' Jay Glazer obtained video of Houston Texans defensive end Antonio Smith swinging at Dolphins guard Richie Incognito with Incognito's helmet.
The video can be viewed here.
The Texans and Dolphins played Aug. 17 in a preseason game.
The two have a history, dating back to last season when Smith claimed Incognito tried to break his ankle on a play — the same play where video showed Smith repeatedly kicking Incognito in the head. Smith was fined $21,000 by the league office.
