Philadelphia Eagles coach Andy Reid signed a three-year contract extension, four days before a showdown with the New York Giants with a possible postseason spot on the line.

Financial terms of the deal weren’t disclosed in a news release from the Eagles, who are 8-4 and tied for first place in the National Football Conference East with the Dallas Cowboys.

The extension, which keeps Reid with the National Football League franchise through 2013, comes a season after his team reached the NFC championship game, eliminating the top-seeded Giants in the first round.

The Philadelphia Eagles have extended the contract of head coach Andy Reid through the 2013 season.

Reid, also the club’s executive vice president of football operations, is in his 11th season as the team’s head coach. He is the second-longest tenured coach in the NFL, behind only Jeff Fisher, who has been with Tennessee for 16 years.

“In every way he is the epitome of what you are looking for in a coach, he’s got passion and all the qualities you look for in a leader,” said Philadelphia owner Jeffrey Lurie. “Andy has said before that he loves it here and wants to remain here, so we got something done since there was no point in waiting.”
