The mother of Tristan Thompson denied an NBADraft.net report that her son had signed with an agent.

“I didn’t sign anything,” Andrea Thompson said by phone from Canada. “We didn’t sign anything. I don’t know where this is coming from. We didn’t talk about anything yet. He’s going to finish this season. We’re just relaxing.”

She added: “Tristan can’t sign. I’m his mom. Tristan is not old enough to sign. He just turned 20. I’m pretty sure you have to be 21.”

Thompson was talking about returning to Texas following their elimination from the tournament.

Another source close to the situation said, “Not at all,” when asked if Thompson had signed with an agent.

Following Ohio State's loss to Kentucky in the Sweet 16, Jared Sullinger promised to stay in school for his sophomore season instead of becoming an early declaration for the 2011 NBA Draft.

"I'm going to be an Ohio State Buckeye next year," he said. "This isn't why I came here, to come in here and see my seniors in here crying. I came here to win a national championship."

Sullinger insists he won't change his mind after he has had more time to reconsider.

"I'm a man of my word," Sullinger said. "I don't change my word and no one changes it for me. This is what I want."

Sullinger was a projected top-10 pick if he were to declare.

Tristan Thompson has informally told the media that he will return to Texas for his sophomore season.

"I'm coming back another year," Thompson told ESPN at the BOK Center in Tulsa.

Thompson averaged 13 points, eight rebounds and more than two blocks a game as a freshman starter.

"I've already signed up for summer classes," Thompson.

Thompson was projected as the 24th overall pick in a recent RealGM mock draft.

Wesley Witherspoon confirmed he will be coming back to Memphis next season.

"I signed to play four years at Memphis and that's what I'm going to do," he said. "It hasn't even crossed my mind to be leaving. I have no idea where people get that."

But Will Barton may be a one-and-done even though he has failed to impress scouts.

"I still could be," he said. "The year isn't over yet. I'm not going to lie, I'm not throwing it out of the woods yet."
