Marcus Smart has received a three-game suspension for shoving a fan during the final seconds of Oklahoma State's loss at Texas Tech on Saturday.

Officials assessed a technical foul but did not eject him, and he remained on the bench until the final buzzer.

"Mr. Smart's actions were a clear violation of the Big 12 Conference's Sportsmanship and Ethical Conduct Policy," Big 12 commissioner Bob Bowlsby said in a statement. "Such behavior has no place in athletics, and will not be tolerated. I appreciate the efforts of Oklahoma State University athletics director Mike Holder in addressing this matter, and believe this is an appropriate response to an inappropriate action."

Smart will miss games against Texas, Oklahoma and Baylor.

"I want to apologize to the fan, whose name is Jeff Orr," said Smart. "I want to apologize to him. I want to apologize to my teammates, to my coaching staff, Coach Ford, my family, Oklahoma State University. This is not how I [conduct] myself, this is not how this program is ran. This is not how I was raised. I let my emotions get the best of me.

"Just can't let that happen again. This is a lesson I'll have to learn from. The consequences that are coming with it, I'm taking full responsibility. No finger pointing. This is all upon me.

"I just want to really apologize to those that are very important to me. I feel like I let my teammates down. These guys mean a lot to me. Not to be able to be out there with them, it hits me in my heart. I have a lot of people that look up to me, a lot of little kids, so once again, I truly apologize. This is not me. I really do apologize for it. Like I said, I take full responsibility and the consequences that come with it."

In a statement released through the school, Orr denied using a slur and said he was sorry for calling Smart a "piece of crap."

"I would like to take this opportunity to offer my sincere apologies to Marcus Smart, Oklahoma State, Tubby Smith and the Texas Tech Men's Basketball program," Orr said in a statement. "My actions last night were inappropriate and do not reflect myself or Texas Tech -- a university I love dearly. I regret calling Mr. Smart a 'piece of crap' but I want to make it known that I did not use a racial slur of any kind. Additionally, I would like to offer my apologies to Texas Tech fans that have been embarrassed by the attention this incident has created."
