Robert Mathis out 2-3 weeks with a sprained knee

The Colts lost a starting running back for a few weeks when Donald Brown had surgery after tearing cartilage in his knee.

He won’t be the only player out of the lineup for some or all of those games. Outside linebacker Robert Mathis is going to be out for two or three weeks with a sprained knee that he suffered in the victory over the Packers.

Mike Chappell of the Indianapolis Star reports that Mathis went to get a second opinion on his knee in Atlanta to confirm the severity of the original diagnosis. He received said confirmation and will be sidelined until the knee has recovered.

It’s a big loss for the Colts, who have gotten five sacks from Mathis in the first four games of the season. They did get Dwight Freeney back from his ankle injury last Sunday, but the two players have long thrived as offenses struggle with figuring out a way to block both of them on passing plays.

With the Jets, Browns, Titans, Dolphins and Jaguars next up on the Colts schedule, there’s a real shot at making a run into position to battle for a playoff spot in the second half of the season. That effort would be a lot more likely to succeed with Mathis in the lineup than it is without him.
