The Philadelphia Eagles lost a potential free agent acquisition Monday when running back Frank Gore backed out of an agreement, an NFL source told the Philadelphia Inquirer.

Gore, the former San Francisco 49er, changed his mind after agreeing on a three-year deal Sunday and is now considering an offer from the Indianapolis Colts, the source said.

NFL Network initially reported the Gore news. It was the first example of a potential free agent who changed his mind after agreeing to terms during the three-day "legal tampering" period before the official start of free agency on Tuesday at 3 p.m.

So the Eagles have to go back to drawing board and find a running back to help offset the loss of LeSean McCoy. They ultimately could find someone to work alongside Darren Sproles and Chris Polk in the draft, but coach Chip Kelly may want to address the need beforehand in free agency.

The Eagles did get some good news Monday when linebacker Brandon Graham, who had all but signed with the New York Giants, decided to stay in Philadelphia after the Eagles sweetened their offer. The 26-year old signed a four-year contract worth $26 million with $14 million guaranteed.

McCourty stays with Pats; Revis likely leaving

Safety Devin McCourty says he's returning to the New England Patriots for five more years, but cornerback Darrelle Revis could be gone.

McCourty agent, Andy Simms, confirmed that his deal would pay $47.5 million over five years, with $28.5 million guaranteed.

Also Monday, ESPN reported that the Patriots have decided not to pick up Revis' $20 million option, instead allowing him to become a free agent.

AEG scraps plans for downtown L.A. stadium

Plans have been abandoned for an NFL stadium in downtown Los Angeles, the developer announced.

As recently as late last year, AEG's Farmers Field project was the front-runner, but with no franchise attached and two competing projects emerging that have NFL owners on board, the downtown plan went into a steep and speedy decline.

"We are no longer in discussion with the NFL or any NFL team," said Ted Fikre, Vice Chairman Ted Fikre of AEG, AEG, which owns the NHL's Los Angeles Kings and the downtown Staples Center, home of the NBA's Lakers and Clippers.

The developer had spent five years and at least $50 million in trying to add the NFL to its arsenal and restore it to the city, but now said it will focus on other downtown projects.

The announcement leaves two clear contenders for the NFL's return to the area for the first time in two decades, both in cities just outside Los Angeles: a stadium in Inglewood proposed in January with the backing of Rams owner Stan Kroenke, and a project in Carson announced last month with the joint backing of the Raiders and Chargers.
