Oklahoma State star Marcus Smart made a dumb move when he shoved a fan behind the basket in the waning seconds of Texas Tech's 65-61 win over the 19th-ranked Cowboys on Saturday night.Smart tried to block Jaye Crockett's dunk attempt from behind with 6.2 seconds to go and tumbled into the front row of the crowd. He was helped to his feet by one man but then got in the face of the Tech fan in a black shirt.The man appeared to say something to Smart, who then shoved him with two hands. The fan stumbled backward but didn't fall.Teammates quickly pulled the angry Smart away from the fracas, and he pointed back in the direction of the fan. Smart was called for a technical foul but was not ejected.A unanimous selection to the preseason All-America team, Smart could face discipline from the Big 12. Texas Tech spokesman Trenten Hilburn said John Underwood, the conference's associate commissioner for basketball, said the league would review the situation."I didn't see it yet. I want to make sure I see it and see what happened," Oklahoma State coach Travis Ford said after the game. "I'm still trying to figure it out."
