Medically red flag doesn’t necessarily mean Sullinger will fall out of first round, but it isn’t a good thing with a lot of solid players with no medical issues available.

Ohio State Buckeyes big man Jared Sullinger has been medically red flagged by NBA doctors, multiple league sources told ESPN.com on Monday.

Sullinger, who is projected to be a lottery pick in the 2012 NBA draft, underwent a series of medical tests at the NBA draft combine a week ago. According to sources, the doctors who looked at Sullinger were concerned with Sullinger’s back.

A number of NBA team doctors have reviewed the information from the NBA and have told their front office staff that Sullinger’s back issues could shorten his NBA career and some have advised their teams not to draft him in the first round.
