OAKLAND — Raider defensive end Trace Armstrong was put on injured reserve Wednesday because of a groin injury, meaning his season is over.
Armstrong, 37, aggravated the injury while warming up before Sunday's 30-10 victory over the New York Jets. He was on the field for one play but spent the rest of the time either standing on the sideline or getting treatment on a medical table behind the bench. He had come back this season from an Achilles' injury that sidelined him for most of the 2001 season.
"I really don't have words to describe it right now," he said. "It's frustrating with where this team is and the opportunities we have. You'd like to be there to help and be a part of it, but this game is nine-tenths misery. That's why you've got to enjoy the high moments because there are usually a lot more bad ones than good ones."
When Tennessee played at Oakland in the third week of the season -- a 52-25 rout by the Raiders -- the home team took a 21-0 lead in the first five minutes. The Raiders had two punt returns for touchdowns and set up another score with an interception by Rod Woodson.
