The Philadelphia Eagles will be without two key defensive players Sunday at Tampa Bay.

Starting free safety Kurt Coleman (sternum contusion) and veteran defensive tackle Mike Patterson (viral pneumonia) were ruled out for the game on Friday. Guard Nate Menkin (strained throat cartilage), running back LeSean McCoy (concussion) and quarterback Michael Vick (concussion) are also out.

Patterson was admitted to a hospital Thursday and was still there as of Friday afternoon.

"He's doing fine," Eagles head athletic trainer Rick Burkholder said Friday in quotes provided by the team. "He's stable. He just got sick and he ended up with pneumonia. We put him in the hospital, where he could get the best care and we can keep an eye on him."

Patterson, 29, has played in just five games this season.

He missed all of training camp and the first eight games of the regular season after undergoing offseason brain surgery to repair a tangle of blood vessels known as an arteriovenous malformation (AVM).

Burkholder said Patterson's illness was not related to the surgery or AVM.

Patterson, the Eagles' first-round draft pick in 2005, had hoped to be able to play against the Buccaneers under new defensive line coach Tommy Brasher. Brasher will coach his first game since being rehired to replace Jim Washburn, who was fired Monday. Brasher previously coached the Eagles' defensive line from 1999-2005. Patterson and defensive end Trent Cole were both rookies in 2005.

"The guys have done pretty well for a short turnaround, trying to get used to (Brasher) and this new system," Cole said Friday in quotes provided by the team. "Mike is not here, but we've got guys that are going to step up. We've got some young guys, and I believe they can get it done."

Coleman was hurt in a 38-33 loss at Dallas this past Sunday night. Colt Anderson will start in his place against the Buccaneers.

Both McCoy and Vick have progressed to phase four of the Eagles' five-step concussion recovery program but still have not passed the NFL's ImPACT test.

Burkholder said Vick is still having trouble tracking with his eyes but is improving. McCoy has been getting headaches at night. Burkholder sent McCoy to visit with concussion specialists in Pittsburgh earlier this week as a precaution.

"I sent (McCoy) to Pittsburgh because I just didn't like the way things were adding up," Burkholder said. "I didn't like how he was getting symptoms at night and not during the day. But everything is fine. There was nothing alarming to me. Both guys are doing great. They're just not cleared for (football) yet."

Menkin, who has been inactive for every game this season, was hit in the throat on the final play of Friday's practice, coach Andy Reid said. He was placed on injured reserve later in the day.
