The Chiefs will have to move forward without one of their top rookies for the foreseeable future.

Kansas City left tackle Josh Simmons is out indefinitely after suffering a dislocated and fractured wrist in Thursday’s Thanksgiving loss to the Dallas Cowboys, NFL Network Insider Ian Rapoport reported, per sources.

Simmons was seen leaving AT&T Stadium in a cast. The rookie LT will undergo an MRI on Friday to seek opinions on treatment options, Rapoport added.
