LAKE FOREST, Ill. -- Veteran Chicago Bears defensive end Jared Allen worked out and attended meetings at Halas Hall on Monday after being inactive in Week 4 due to a reported case of pneumonia.

Allen’s absence on Sunday in the Bears’ 38-17 defeat to the Green Bay Packers snapped a streak of 113 consecutive starts. The five-time Pro Bowl defensive end hadn’t missed a game since Week 2 of the 2007 regular season.

“He was working out,” Bears head coach Marc Trestman said. “It’s going to be day-to-day and we’ll see where he is on Wednesday. It was good to see him in the building, good to see him in all the meetings. He got some work in the weight room. That’s encouraging.”

Trestman declined to elaborate the amount of weight Allen lost since he contracted the illness.

“He always looks skinny to me,” Trestman smiled.

The Bears' next practice is scheduled for Wednesday in advance of Sunday’s road matchup versus the Carolina Panthers.
