AP source: Colts CB Jackson out for season
A person with knowledge of the injury says Indianapolis Colts cornerback Marlin Jackson will miss the rest of the season after tearing the ACL in his left knee.
The person spoke to The Associated Press on condition of anonymity because the Colts had not announced the injury. It occurred during Thursday's practice.
The injury was first reported by ESPN and the Indianapolis Star.
Jackson made 23 consecutive starts at cornerback before tearing the ACL and meniscus in his right knee during a no-contact practice in October 2008.
He had missed the past three games with a strained ACL in his right knee. Jackson's newest injury came a day after the Colts placed linebacker Tyjuan Hagler on injured reserve with a ruptured biceps.
The team declined to comment on Jackson's injury.
