Oakland Raiders quarterback Jason Campbell was a limited participant during this week's practice, and is listed as "Questionable" on the final injury report of the week.

As long as there are no setbacks, however, he'll start on Sunday afternoon against the Denver Broncos.

"I thought Jason was pretty close today, so if it stays that way, I think it would be him--again, with no setbacks," Raiders head coach Tom Cable said on Friday according to Jerry McDonald of the Bay Area News Group.

Campbell (6-5, 230) has started three of the four games he's been active this season, completing 56.0% of his 91 pass attempts for 509 yards with a pair of touchdowns, four interceptions, and a passer rating of 61.1.

The Raiders are 1-2 when Campbell starts, and the former first-round pick from Auburn replaced an injured Bruce Gradkowski to lead Oakland to a come-from-behind 35-27 win over the San Diego Chargers in Week 5.
