It looks as if Jared Sullinger isn't the only big-time NBA draft prospect to have medical issues potentially hurt his stock.

Multiple league sources say NBA team doctors are concerned about a meniscus issue in the knee of Baylor forward Perry Jones III.

While opinions among NBA doctors vary on the ramifications of the issue, some teams believe the knee could pose a problem down the road and at some point require surgery.

Not all teams have the same degree of alarm, but the concerns have caused Jones' stock to slide from the mid- to late-lottery portion of the draft into the late teens and early 20s of the round.

Jones' agent, Bill Duffy, declined comment.
