One of the other storylines in the first round of the 2010 NFL draft was Sergio Kindle's tumble.

The Texas pass rusher was expected to be a first round pick. A popular landing spot for him in mock drafts was the Dolphins 12th pick.

Of course that didn't happen and he fell all the way out of the first round. Now, we find out why that might have happened from a report on Rivals.

"There are a handful of teams who have graded Kindle as a 'serious' medical risk because of his knee, which one team said looks like it could require Kindle to have microfracture surgery," the report stated

"Microfracture is a surgery to create cartilage in the knee when it becomes a bone-on-bone situation," he continued. "It's a surgery athletes tend to have near the end of their careers. Not at the beginning. According to some teams, Kindle's medical exams showed a series of trauma on the knee that could limit his career."

This would explain his fall out of the first round.

Now the question becomes how much farther he'll fall.
