Detroit Lions President Matt Millen has agreed to a five-year contract extension, owner William Clay Ford Sr. announced yesterday.

Millen, who is in the fifth and final season of his original contract, said that he agreed to the deal last month, but the announcement was delayed to avoid taking the focus off the team. The extension will run through the 2010 season.

The Lions have gone 16-48 since Millen was lured out of the Fox television booth, including a league-record 24-game road losing streak.

But Detroit has had more success under Coach Steve Mariucci, going 11-21 over the past two seasons and ending the road losing streak in last season's opener at Chicago.

* SEAHAWKS: First-round draft pick Chris Spencer signed with Seattle after missing the first five days of training camp.

Spencer, a center out of Mississippi, joined his Seahawks teammates at the campus of Eastern Washington University. He was the No. 26 overall pick in April's draft and the last unsigned rookie for the Seahawks.

"Every day, I woke up and had my bag sitting at the door," said the 6-foot-3, 305-pound Spencer, who passed time during his holdout at his house in Kirkland, Wash., near Seahawks headquarters. "All I had to do was grab it when my agent called."

Spencer signed a five-year contract worth $7.4 million, with an additional $2.3 million available in incentives.

* JETS: Quarterback Chad Pennington was held out of the team's afternoon practice after throwing passes for five straight days.

Coach Herman Edwards said Pennington had no soreness in his surgically repaired right shoulder, and just wanted to give the quarterback a day to rest.

"He threw five days in a row, and that's the first time he's ever done that," Edwards said. "Five days in a row is a lot of throwing, in my estimation."

* BEARS: Defensive back Jerry Azumah, a Pro Bowl kickoff returner two years ago, had arthroscopic surgery on his right hip and was expected to miss three to four weeks.

Coach Lovie Smith said he was expecting Azumah back for the Sept. 11 season opener at Washington.

"They went in and cleaned it out. That's basically about all they were able to do and needed to do," Smith said.

* GIANTS: Wide receiver Plaxico Burress missed practice with a strained hip flexor and Coach Tom Coughlin said the injury is expected to keep the free agent acquisition sidelined for a few more days.

Burress hurt his left hip during practice Tuesday. Yesterday he rode a stationary bike but did not take part in drills.

* PANTHERS: Wide receiver Keary Colbert missed practice with a strained right hamstring. Colbert, listed as a starter so far in training camp, was injured on Tuesday during one-on-one drills. Colbert said it was stiff when he woke up yesterday.

* BROWNS: Cleveland signed two players who played for Coach Romeo Crennel when he was New England's defensive coordinator, defensive back Antwan Harris and defensive tackle Ethan Kelley.
