Colts wide receiver Anthony Gonzalez suffered a right knee injury during Sunday's 14-12 season-opening victory over the Jacksonville Jaguars and could be out several weeks. NFL Network's Jason La Canfora reports that Gonzalez suffered a strained ligament in the knee, with a preliminary diagnosis of missing 2 to 6 weeks, according to a league source. The Colts will do more testing on Gonzalez on Monday and monitor any swelling, but they expect the receiver to miss at least a few weeks.
