Eagles fullback Jon Ritchie underwent successful surgery yesterday to repair the anterior cruciate ligament in his left knee, the team said.
Team physicians Peter DeLuca and Paul Marchetto performed the surgery at Hahnemann University Hospital.
Ritchie, 30, who was injured in the 30-13 win over Detroit on Sept. 26, will be lost for the remainder of the season.
Although he had no rushing attempts, he had four catches for 36 yards in the Eagles' first three games. He was used primarily as a blocking back.
