HARTLAND, Wis. (AP) _ Mark Chmura of the Green Bay Packers was arrested early today but police did not immediately say why he was jailed.

Chmura, one of the NFL's best tight ends, was booked at Waukesha County Jail, less than an hour's drive from Milwaukee, said jail clerk Lorrie Granstrand. No other details were released.

The Hartland Police Department planned a news conference today regarding the arrest.

A Packers spokesman said the team will comment after it has more information. No one answered the phone listed for Chmura's agent, Eric Metz.

Chmura joined the Packers in 1992 but missed most of last season because of a neck injury during the second game. He was at last month's minicamp, returning from what some feared was a career-ending injury.

The 31-year-old player is entering his ninth NFL season.

``I'm actually glad I'm here,'' he said during the Packers' first minicamp under coach Mike Sherman. ``I appreciate things more. It's been a long year, a long wait. It was good to get out there.''

In February, wide receiver Antonio Freeman was sentenced to a year of probation for obstructing police in a Green Bay traffic accident. Former wide receiver Charles Jordan was fined $5,000 for lying about the accident.
