Ryan Mathews questionable for Denver Broncos clash

San Diego Chargers running back Ryan Mathews is questionable for his side's AFC divisional round playoff clash with the Denver Broncos on Sunday.

Mathews injured his ankle in his side's win over the Cincinnati Bengals last week as he missed the second half of the victory, and he has been limited in his side's practice sessions in the last few days.

Center Nick Hardwick is also questionable after sustaining a concussion in the win at Paul Brown Stadium, while fellow lineman Jeromey Clary is struggling with a shoulder problem.

Wide receiver Eddie Royal, offensive lineman DJ Fluker and defensive tackle Sean Lissemore round off the players listed as questionable, but are expected to play for Mike McCoy's side against the Broncos.
