Clemson defensive end Da’Quan Bowers isn’t the only prospect that might see his draft stock fall over these next couple of weeks due to concerns about a knee injury.

According to NFL Network’s Mike Lombardi, teams have growing concerns about the health of Alabama running back Mark Ingram, who had his knee scoped prior to the 2010 season. After rushing for 1,658 yards and a 6.1 YPC average on 271 carries in 2009, the former Heisman Trophy winner was limited to just 875 yards on 158 totes a year ago.

I’ve released three mocks and in all three of them, I’ve had the Dolphins selecting Ingram with the No. 15 overall pick. There’s a real possibility that Ronnie Brown and Ricky Williams (who are both free agents) have played their last downs in Miami, making the selection of Ingram a popular one in many mocks – not just mine.

But if his knee is a concern for some teams, then he could easily fall into the second round. Plus, there’s growing sentiment that the Dolphins want a home run threat, which doesn’t exactly describe Ingram’s game. If that’s the case, then maybe the Dolphins will look to nab someone like Oklahoma State’s Kendall Hunter, Oklahoma’s DeMarco Murray or UConn’s Jordan Todman in the middle rounds.

If Ingram does slip into Round 2, it’ll be interesting to see whether or not a running back will even be selected in the first. Mikel Leshoure of Illinois is viewed as a potential first round pick, but Ingram is listed ahead of him in most pundits’ rankings so he may fall, too. It isn’t a great year for running back-needy teams, although there are always bargains in the middle rounds.
