The two-time Pro Bowl defensive end did not play in Sunday's 34-3 loss to New Orleans when Saints quarterback Drew Brees passed for 320 yards and three touchdowns. Brees was sacked just one time and compiled a rating of 144.4.
Burgess, who has led or tied for the team lead in sacks since signing with Oakland prior to the 2005 season, wore a thick bandage around his arm in the locker room after the loss to the Saints and is being listed as week to week by the Raiders.
Veteran Kalimba Edwards started against New Orleans in place of Burgess and had two tackles but failed to lay a hand on Brees. Oakland's only consistent pressure came from defensive tackle Tommy Kelly, who had the team's lone sack and recorded two hurries.
Rookie Trevor Scott also got some playing time but the Raiders will be in a bind if Burgess has to miss any extended time.
"Kalimba can do it," interim coach Tom Cable said. "It's a matter of finding someone at that left end spot. Maybe it's a combination of guys, with Trevor Scott and Jay Richardson. But not having Derrick there, that certainly hurts, no question."
Cable was encouraged by the progress being made by running back Darren McFadden, who has been slowed by a turf toe injury. McFadden, who ran for 30 yards on eight carries against New Orleans, didn't need his protective walking boot Monday and possibly may rejoin full workouts this week.
