Several teams have been concerned Kindle could need microfracture surgery on his knee early in his career, the source said, which might explain his slide out of the first round of the NFL draft.
The Baltimore Ravens apparently weren't too concerned with Kindle's health, picking him at No. 42 in the draft's second round Friday.
Rivals.com reported Thursday that, according to some teams, Kindle's medical exams showed trauma on the knee that could limit his career.
Several teams graded Kindle as a "serious" medical risk because of the knee. One team said it could require microfracture surgery, according to the report.
Any surgery would not happen immediately or prevent Kindle from playing his rookie season, the source told Schefter.
