McNabb, who led the Eagles to 100 victories, five NFC title games but only one losing Super Bowl appearance, played 11 of his 13 seasons for Philadelphia. He's currently an analyst for the NFL Network.
The 36-year-old, who played one season with NFC East rival Washington and a final season with Minnesota in 2011, is the Eagles' leader in several passing categories, including touchdowns (216), completions (2,801) and yards (32,873).
He will make an official announcement about his retirement on Monday, the Eagles announced on Twitter.

McNabb finished his career with 37,276 yards passing, which ranks 17th in NFL history, and 3,469 yards rushing, which ranks sixth among quarterbacks. His best season came in 2004, when he completed a career-best 64% of his passes for 3,875 yards and 31 touchdowns with only eight interceptions as the Eagles went 13-2 in his 15 starts.
McNabb tweeted that he was looking forward to this weekend with Philadelphia players and fans.
