Jared Sullinger, the Ohio State star who is projected as a lottery pick in the NBA Draft next week, has been medically red-flagged by NBA doctors, according to an ESPN report.

The target of concern is Sullinger's back. Team physicians who, according to ESPN, have studied results of tests taken last week have informed their front-office people that Sullinger's back problems could shorten his NBA career.

“He had a bulging area that was due to his hamstring and quads being so tight,” Sullinger's father, Satch, said. “It pulled on his hip flexor and he's been taking care of it to loosen it. You can call it a red flag if you want. But it's tight hamstring and tight quads. He's been to doctors, he's doing yoga and deep tissue massage. The flexibility is helping take the pressure off the area.

“We've got nothing to hide. At this stage it's all about what they can't do. Jared is a skilled player. A two-time All-American. He can play.”

Ohio State Coach Thad Matta texted ESPN: “Jared is fine. He's moving better than I've ever seen him move.”

Sullinger has worked out for New Orleans, Golden State and Portland and is expected to meet with Toronto, Cleveland and Detroit.

Sullinger's agent, David Falk, told SI.com: “Jared has consulted with one of the foremost specialists of backs and spines, who has vast experience treating professional athletes. He has explained to us that Jared had extremely tight hamstrings that became tight because he had suffered an injury — that I don't think he was aware of — to his hamstring. He needs to maintain a vigilance with his flexibility. And if he does that, and keeps his weight at an appropriate level, then he should have absolutely no problems over the next 15 years.”
