Preseason 'footbrawl'

It seems there hasn't been a day that's passed without a scuffle at NFL training camps this summer. Here's a list of some of the more memorable ones:

Panthers: QB Cam Newton runs down CB Josh Norman after getting stiff-armed following an interception. Newton finds himself at the bottom of the pile with his helmet off and the two are separated by teammates. Results: No injuries reported, but Newton says he would do it again, saying "it's football. Let's not get it twisted about football". Norman has not spoken to the media.

Jets: QB Geno Smith is sucker-punched by LB Ikemefuna Enemkpali in the locker room over something that coach Todd Bowles said had nothing to do with football and was "very childish." Results: Smith, entering his third season, will require surgery to repair the injuries and is out 6-10 weeks. Enemkpali was immediately released.
