Raiders LB Romanowski done for season

OAKLAND, California - A trying season has come to a premature end for Oakland Raiders linebacker Bill Romanowski.

The Raiders placed Romanowski on injured reserve Thursday night, ending the season for the 16-year veteran linebacker, who had missed their last four games after suffering a series of concussions.

Romanowski, 37, will remain with Oakland for the rest of the season as a defensive adviser, coach Bill Callahan said.

"I don't think there's been a more dominant player than Bill at that position," Callahan said.

Romanowski, who was in his second season with Oakland after playing for Philadelphia, San Francisco and Denver, has yet to announce whether he will retire. He had undergone a series of tests in recent weeks to determine whether it was safe for him to return to the field, but doctors advised him against doing so.

"I was still optimistic that the results would show he could possibly play," Callahan said. "But unfortunately not."

The volatile Romanowski made headlines in training camp, when he ripped the helmet off teammate Marcus Williams and punched him in the face, breaking his orbital bone and forcing him on injured reserve.

Though Romanowski apologized, Williams sued the linebacker last week for alleged battery, negligence and intentional infliction of emotional distress.

Romanowski won a pair of Super Bowls with both the 49ers and the Broncos.
