The Cincinnati Bengals lost Vontaze Burfict to what looked like a leg injury during Monday’s training camp practice.

Burfict left the practice field on a cart so he could get back into the locker room before other players:

Burfict had initially struggled with a hamstring issue he suffered during a conditioning test before training camp started. Once activated, he said he planned on playing in preseason games.

Regardless of whether he suits up in an exhibition, Burfict is suspended for the first four games of the regular season for a violation of the league’s policy on performance-enhancing drugs.
