EAST RUTHERFORD, N.J. -- The New York Giants suffered another tough loss in what may have been Tom Coughlin's final game.

Former Giant Walter Thurmond scored on an 83-yard interception return in the third quarter and the Philadelphia Eagles added to Coughlin's season-long frustrations with a 35-30 victory on Sunday.

It was the third straight loss for the Giants (6-10) and finished a third straight losing season and a fourth straight year out of the playoffs.

After meeting with Eagles interim coach Pat Shurmur at midfield, Coughlin walked off the field, waving to the crowd just before walking into the tunnel.

Coughlin, who led the Giants to two Super Bowl titles in his 12 seasons, has a year left on his contract. His future is expected to be decided soon by co-owners John Mara and Steve Tisch.

The 69-year-old might retire and end his 20-year NFL head coaching career.
