ARLINGTON, Texas -- Raiders defensive end Greg Ellis didn't play in the second half against Dallas on Thursday because of swelling in his left knee and lower leg.
Ellis was one of the captains and started against the team he played with for 11 seasons. He was in on two tackles in the first series of Oakland's 24-7 loss.
The medical staff tried to drain the knee at halftime. Ellis said there was also swelling in his calf and shin that prevented him from returning in the second half.
"If the swelling was just in my knee, I probably would have been able to go out there," said Ellis, who was released by the Cowboys in the offseason. "But it went down my shin and calf, and you can't drain that."
Ellis, who also has shoulder problems this season, missed one game after he had surgery on his left knee Nov. 4. He returned Sunday and had a sack against Cincinnati.
"It's extremely disappointing," Ellis said. "I wanted to help my team. I hate we lost, but it bothers me more that I wasn't able to go out there and finish it."
