Cardinals' rookie guard Bisontis sidelined by torn MCL
Arizona Cardinals rookie offensive guard Chase Bisontis has torn his MCL, MRI-confirmed and requiring surgery, likely ending or severely limiting his rookie season. He was competing for the starting right guard spot when a Raiders defender fell into his knee in the third quarter of a preseason game. The injury adds to a history of preseason injuries sidelining Cardinals' rookie offensive linemen in recent years.
