Campbell, who reportedly suffered a dislocated shoulder, was replaced by backup Kyle Boller for the rest of the half.
In terms of fantasy points per game, Campbell was ranked 13th among quarterbacks in Yahoo! Sports leagues, so it's not like he was racking up the points anyway.
There's a chance a prolonged absence could dig into star running back Darren McFadden's production if Boller struggles. If Boller isn't able to do a decent job of leading the Raiders down the field, defenses could then start stacking the box. Then again, McFadden is now a superstar and superstars have a way of overcoming the odds and producing no matter what.
Who's the Backup?
Boller was selected as a first-round pick back in 2003 out of Cal. Since then, he's largely been a disappointment, his best season as a pro coming in 2004 when he tossed for over 2,500 yards, 13 touchdowns and 11 interceptions.
Upon taking over for Campbell, Boller went 0-of-2 and was sacked once.
If Campbell is forced to miss significant time, this could be a big blow for the Raiders.
Campbell has never been a stellar quarterback, but he's proven with the Raiders and Washington Redskins that he can be effective, and he's a veteran that knows how to control the clock.
I'm putting this at a 7 out of 10 given the Raiders have Boller backing Campbell up. The Raiders still have McFadden, who has the ability to carry an offense, but, again, it's going to be hard for him to carry them if the entire defense is focused on him.
Timeline for Return
It looks like Campbell is going to be held out of the rest of Sunday's game against the Browns. His return is doubtful and he could be out for an extended period of time.
What They're Saying
I'll spare you the swear words being thrown around Raiders Nation after Campbell's injury, but it's safe to say Raiders fans are not happy.
Of course, it took all of a few minutes for people to start bringing up Terrelle Pryor. Sigh...
