After a rash of fights among teammates in training camp, including the one that saw former Jets linebacker Ikemefuna Enemkpali break quarterback Geno Smith's jaw on Tuesday, the NFL has sent a reminder to team executives, general managers and head coaches about the prohibition against fighting.
NFL vice president Troy Vincent wrote the letter, which was distributed on Friday, and cited the rules governing fighting in the 2015 League Policy for Players.
"There have been several recent incidents of fighting among teammates and one involving opposing teams," said Vincent, referring to the fights, as well as a series of brawls that occurred when Washington and the Texans held joint practices last week.
