GREEN BAY, Wis. — The Green Bay Packers announced the signing of Ryan Grant on Sunday, a day after the running back and team agreed to a four-year deal worth up to $30 million.

Grant was in uniform and pads Sunday night for the Packers' annual "Family Night" scrimmage, but was not expected to participate in live action.

Grant was an exclusive-rights free agent but refused to sign his tender offer from the team in hopes of working out a long-term deal. He did not report to camp earlier this week, and talks between the two sides had stalled until late in the week.

Grant, acquired by the Packers in a trade with the New York Giants just before the start of last season, became the starter in the second half of the season and rushed for 956 yards and eight touchdowns. He added 201 yards and three touchdowns in Green Bay's playoff victory over Seattle.

To make room for Grant on the 80-man roster, the Packers waived long snapper Thomas Gafford — ending Gafford's competition with J.J. Jansen to replace veteran long snapper Rob Davis, who retired after last season to take a job in the Packers' front office.

Green Bay will have to make another move after Brett Favre is reinstated to the team's active roster Monday.

McGAHEE MIGHT MISS RAVENS PRESEASON OPENER: Baltimore Ravens running back Willis McGahee might miss Thursday's preseason opener against the New England Patriots because of an ailing left knee,

"Right now, we need to get the fluid out of his knee and get that thing settled down a little bit," Ravens coach John Harbaugh said Sunday.

Rookie Ray Rice could get the start in his NFL debut because of the injury to McGahee.

Tight end Todd Heap also missed practice with a right calf injury, which is not believed to be serious.

"I think his is more of a fatigue thing," Harbaugh said. "He's got some kind of a tweak in there, but he's fine."

Wide receiver Mark Clayton (shoulder) and running back Cory Ross (toe) returned to practice.

BURRESS DOES LIGHT RUNNING FOR FIRST TIME: Receiver Plaxico Burress did some light running Sunday night for the first time since the New York Giants opened training camp at the University at Albany more than a week ago.

Burress, who has missed all 14 practices, has been bothered by a problem with his right ankle that's not related to the one he had a year ago.

Burress, who caught the game-winning touchdown pass in the final minute of the Super Bowl, was examined by team doctors on Sunday.

The veteran receiver led the Giants in receptions while catching a career-best 12 touchdown passes. He refused to practice during a minicamp in June to protest the team's refusal to give him a new contact. He was fined $25,000.

Drew Rosenhaus, his agent, had contract talks with the Giants last week. Burress has three years left on a deal that will pay him $3.25 million this season.
