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.
