This hasn't been a good week on the medical front for the Indianapolis Colts.

The team has announced today that safety Bob Sanders will require season-ending surgery on a torn biceps. Last night, the team announced that cornerback Marlin Jackson will miss the remainder of the season with a torn ACL.

In addition to losing half of their starting secondary for the remainder of the season, starting cornerback Kelvin Hayden will miss the next 3-4 weeks with a knee injury as well.

Earlier in the week, the Colts lost LB Tyjuan Hagler for the season with a biceps injury.

Aside from the losses on defense, receiver Anthony Gonzalez, who hasn't played since suffering a knee injury in week one, had arthroscopic surgery yesterday and will miss (at least) a few more weeks.

Even without Gonzalez, the Colts lead the NFL in passing offense (321.3 yards per game).

However, it will be much more challenging for the Colts on the defensive side of the ball over the next few weeks.

On the season, the Colts' pass defense ranks seventh in the NFL allowing 180.1 yards per game. They have allowed a league-low of three touchdown passes this year.

But they face the Houston Texans this week and New England Patriots next week.

Houston's Matt Schaub leads the NFL in passing yards (2,342) and is tied for the league lead in touchdowns (16). New England's Tom Brady ranks fifth in passing yards (2,032) and is tied for fourth in touchdowns (15).
