Jacksonville Jaguars runningback Rashad Jennings injured his knee in the preseason game against the Buffalo Bills. He's since been on crutches and announced on twitter earlier he would be placed on injured reserve. This isn't much of a surprise, given Jennings has been on crutches since earlier in the week. The injury is to his knee, however it's unclear if it's a torn ACL, MCL, or what exactly it is.
This is a big blow to the Jaguars, because even though it looks like Maurice Jones-Drew will be just fine, the team planned to increase Jennings workload to help keep Jones-Drew fresh down the line. Jennings was good at just about everything and was a bigger back with speed. It looks like UDFA runningback Richard Murphy will make the final roster over DuJuan Harris, who's been released and headed to the practice squad. As I mentioned on twitter, it's likely the team kept Murphy over Harris because of his size and ability in pass protection. Harris is like another Deji Karim, and the team needed a bigger back.
