Less than nine months after he had surgery to correct a torn anterior cruciate ligament, Jamaal Jackson underwent a procedure Tuesday to have his right triceps tendon repaired, the Eagles said.
The center, who suffered the injury during the second quarter of Sunday's season opener against the Green Bay Packers, was placed on injured reserve Monday, ending his season. Backup Mike McGlynn replaced Jackson in the game and will start Sunday when the Eagles travel to Detroit.
Jackson tore the ACL in his left knee in the second-to-last game of last season but was able to return in time for the opener. He suffered a similar injury to his left triceps in the 2004 preseason and missed the rest of the year.
