Smart opened the press conference in Stillwater with an apology.
"First off, I want to apologize to the fan and I want to apologize to my teammates and the fans," started Smart. This is not indicative of my actions. This is not me."
Oklahoma State head coach Travis Ford defended Smart but also said the punishment was deserved and stood by the Big 12 while defending Smart as a good person and that was an uncharacteristic action by Smart.
"I know Marcus Smart. I've been around him for two years and that was not one of his finer moments, but he has had a lot of moments," said Ford. "That is not who he is.
"He hurts from what happened and he hurts for his teammates and those are the reasons that I love Marcus Smart. When he comes back, he will come back in a big way.
"I do think he has learned a valuable lesson. He will learn from this and be better person," added Ford.
The games a Smart will miss include a road game on Tuesday at Texas, a home game next Saturday with Oklahoma, and a road game at Baylor (Feb. 17).
