MILWAUKEE (AP) _ Mark Chmura retired from professional football Monday, four months after he was acquitted in a sexual assault case.

Chmura's lawyer, Gerald Boyle, said the one-time Pro Bowl tight end for the Green Bay Packers wanted to play only for his former team ``and they did not make him an offer.''

Boyle said other teams made offers to Chmura, but he declined them.

The Packers waived Chmura a year ago while charges against him were pending. He sat out the 2000 season.

He was acquitted in February on a charge of second-degree sexual assault. A girl who was 17 at the time accused him of assaulting her in a bathroom during a post-prom party in April, 2000.

In 1998, Chmura's last full season, he made the Pro Bowl. A neck injury kept him out for the entire 1999 season.

Also on Monday, Chmura pleaded no contest in a Waukesha court to contributing to underage drinking and agreed to pay a fine of $704. Boyle made the plea on his behalf.

Chmura's agent, Eric Metz, said Monday he knew nothing of the announcement.

``There's nothing to report, nothing I can talk about,'' Metz said.

Chmura reportedly sent a letter to Packers coach-general manager Mike Sherman announcing his retirement, with copies sent to the NFL Players Association and the NFL Management Council. WTMJ-TV obtained a copy of the letter.
