During Saturday night's Texans-Dolphins preseason game, a one-on-one between defensive end Antonio Smith and offensive guard Richie Incognito escalated when Smith ripped Incognito's helmet off of him and swung it at his head, just missing the target.

The incident was barely visible on the game's broadcast, but Jay Glazer of FOX Sports was able to scare up video that offered a better angle of what happened. Smith was not flagged on the play, but the NFL will investigate.
