Jason Campbell has left the Raiders' Week 6 game against the Browns with an apparent shoulder or collarbone injury after hurt his shoulder on an awkward landing on this scramble.
Campbell is being examined the sideline after the injury, and the Raiders have inserted Kyle Boller for him. Campbell was six for nine through the air for 52 yards before leaving.
Campbell has led the surprising Raiders to a 3-2 record in 2011, and the wide open AFC West appeared to be within Oakland's reach.
Boller inspires few as the Raiders' second-string quarterback, but the emergency quarterback is even less proven — Terrelle Pryor, who spent most of the early part of 2011 in NCAA limbo, is Boller's understudy.
