PHILADELPHIA -- Koy Detmer returned to the Philadelphia Eagles on Tuesday to provide insurance at quarterback going into the playoffs.

Detmer will be the No. 3 quarterback behind starter Jeff Garcia and backup A.J. Feeley. After Donovan McNabb went down with a season-ending knee injury in Week 11, the Eagles added Omar Jacobs to the practice squad.

To make room for Detmer on the roster, cornerback Bruce Perry was released.

The 33-year-old Detmer spent nine seasons with Philadelphia after being selected in the seventh round of the 1997 NFL draft. He was cut in training camp and was out of football this regular season.

Detmer has started eight games in his career while serving mostly as a backup to McNabb and a holder for kicker David Akers. He's completed 52 percent of his passes (184-for-354) for 1,944 yards, 10 touchdowns and 14 interceptions.

Detmer's most memorable performance came in a Monday night game against San Francisco in 2002. One week after McNabb broke his ankle, Detmer threw for 227 yards and two TDs and ran for another before leaving with a dislocated elbow in the third quarter of a 38-17 win over the 49ers.

Despite losing McNabb, the Eagles went 5-1 behind Garcia and captured their fifth NFC East title in six years. Philadelphia (10-6) hosts the New York Giants (8-8) on Sunday.
