08:04 AM ET 04.14 | After undergoing knee surgery last summer, Mark Ingram still went on to average more than 5.5 yards per carry. But there have been rumors that the long-term stability of Ingram's knee is tenuous. And NFL Network's Mike Lombardi reported something that may substantiate that speculation on Wednesday evening's Path to the Draft. "I've had two teams tell me the knee is very bad," said Lombardi. "He won't be on their boards. These are teams that need running backs." NFL Network's Mike Mayock didn't go as far as Lombardi, but did acknowledge Ingram is in danger of falling out of round one, where he's so often projected. "Even fully healthy, I have concerns about whether he's a first-round pick," said Mayock of Ingram.
