NFL Investigating Preseason Helmet-swinging Incident
AUG 19, 2013 4:20p ET
In the video,Texans defensive end Antonio Smith gets into a scuffle with Miami offensive lineman Richie Incognito, eventually ripping off his helmet and swinging it at him, narrowly missing Incognito's head in the process.
No penalty was called on the play.
Miami head coach Joe Philbin has already contacted the league about a possible fine and/or suspension.
The NFL could fine Smith as the helmet cannot be used as a weapon, by rule.
And there is history between the two: last season, Smith was fined $21,000 by the NFL - reduced to $11,000 after an appeal - for kicking Incognito while he was on the ground.
