CHARLOTTE, N.C. -- How long Carolina Panthers quarterback Cam Newton plays in Sunday night's preseason game against the Kansas City Chiefs will have more to do with how well his restructured offensive line plays than him. Coach Ron Rivera reiterated after Friday's practice that he didn't want to do anything to put the first pick of the 2011 draft under pressure to re-injure the left ankle that was surgically repaired in March. So if Newton finds himself under a lot of heat and forced to scramble, his time on the field likely won't last past the first quarter.via - NFL Nation
