Mark Hatley, the Green Bay Packers' vice president of football operations, has died at age 54.

The cause of his death was not known, and the Brown County (Wis.) medical examiner did not return a call from the Associated Press.

Hatley was second in command behind Coach-General Manager Mike Sherman on personnel matters. He was responsible for overseeing the team's scouting efforts.

"Today, the Green Bay Packers not only lost a valuable member of its team but also a trusted and loyal friend," Sherman said in a statement he read at team headquarters yesterday. "Mark Hatley loves his family, he loved his friends and he loved football."

Hatley's agent, Bob LaMonte, said he received a call from Sherman yesterday morning informing him of Hatley's death overnight.

* DOLPHINS: Ricky Williams could be forced to give back more than $8 million already paid to him because he retired before the expiration of his contract.

Because of penalty clauses included when Williams's contract was reworked two years ago, the team could try to recoup $5.3 million in incentive money, said sources familiar with the terms who requested anonymity. The Dolphins also could seek $3.3 million of the $8.8 million signing bonus Williams received when he joined the New Orleans Saints in 1999, the sources said. The Dolphins said they've made no decision about whether to pursue the matter.

* COWBOYS: The team waived Chad Hutchinson, ending an attempt to turn the former major league pitcher into a starting quarterback. The team also said back surgery on safety Darren Woodson went well. Woodson had a herniated disk removed from his lower back. He is expected to be out up to eight weeks.

* EAGLES: The team agreed to terms with four draft picks. Cornerback Matt Ware, a third-round pick from UCLA; safety J.R. Reed, a fourth-round selection from South Florida; offensive lineman Trey Darilek, a fourth-round choice from UTEP; and fullback Thomas Tapeh, a fifth-round pick from Minnesota, each agreed to four-year contracts.

* RAIDERS: The team released cornerback Rod Woodson, who is third in NFL history with 71 interceptions, after he failed a physical examination. Woodson, 39, missed six games last season because of torn cartilage in his left knee.

* TEXANS: Safety Marcus Coleman was sentenced to three days in jail and fined $2,000 for drunk driving.

* FALCONS: Wide receiver Michael Jenkins, one of Atlanta's first-round draft choices, reached a multiyear agreement with the team.

* JETS: The team signed top draft choice Jonathan Vilma, a linebacker, two days before camp opens.
