FLORHAM PARK, N.J. — The NFL assessed $125,000 in fines to the New York Jets and former coach Eric Mangini yesterday for violating the league's rules on injury reporting with former quarterback Brett Favre last season.

The Jets failed to place Favre, now with the Minnesota Vikings, on the injury report during the final month of last season even though he had a torn biceps tendon.

The league announced it had fined the Jets $75,000, and Mangini and Jets general manager Mike Tannenbaum $25,000 apiece. Mangini now coaches the Cleveland Browns.

"We have been fully cooperative with the league throughout this investigation and respect their decision," the Jets said in a statement.

Mangini wants to put the situation behind him.

"I have worked with the league on this matter and now consider it closed," he said in a statement. "My focus is on our preparations for the Broncos."

Hiding injuries could affect an opponent's preparation and the NFL has stepped up policing such practices. Commissioner Roger Goodell said Monday that the case would be an opportunity for the league to stress that all teams must abide by the injury report rules.

Last week, Tannenbaum admitted the Jets should have listed Favre as "probable" on their injury reports.

FB SELLERS GETS NEW DEAL

Mike Sellers' offseason boycott has paid off, helping the Washington Redskins fullback land a contract extension.

The Pro Bowl fullback confirmed yesterday he finally swayed owner Dan Snyder to offer a new deal. Its total value is about $6.9 million over the next six years, but the final two years are voided automatically if Sellers is still on the roster after the 2012 season. Essentially it is a four-year deal with $1 million guaranteed: a $600,000 signing bonus and a $400,000 option bonus next year.

Sellers stayed away from offseason workouts to voice his displeasure over his previous contract. He was coming off his first Pro Bowl season and was elected a team captain in preseason.

SHORT SNAPS

Bills: Buffalo starting middle linebacker Paul Posluszny is expected to miss about six weeks after having surgery to repair a broken bone in his left arm. Posluszny was hurt in the first half of the Bills' season-opening 25-24 loss at New England on Monday.

Chiefs: Matt Cassel appeared to be running more briskly in practice yesterday morning, creating hope Kansas City's No. 1 quarterback might start Sunday against the Oakland Raiders. Coach Todd Haley said Cassel, who injured his left knee in a preseason game Aug. 29 and sat out the season opener at Baltimore, would be listed as questionable.

Eagles: Philadelphia quarterback Donovan McNabb did not practice yesterday because of his cracked rib and it is still not known if he will play against New Orleans on Sunday. "He's making some progress," coach Andy Reid said. "It's too early to say anything right now. We'll just see how he does over the next couple of days."

Patriots: New England inside linebacker Jerod Mayo suffered a sprained medial collateral ligament and could miss up to eight weeks, the Boston Globe reported. Mayo did not work out with the team yesterday, two days after being injured in a 25-24 win over the Buffalo Bills.

Seahawks: Seattle got worse news than it expected on starting linebacker Leroy Hill, who left last weekend's game against St. Louis with a groin injury. Coach Jim Mora said that Hill will be out until at least November, after tests showed more extensive damage than first believed. Hill has a partially torn muscle and may need surgery.
