After a vulgar Snapchat video circulated through social media Thursday, incoming Kansas transfer K.J. Lawson issued an apology through Twitter.

Lawson, a 6-foot-7 forward, made disparaging comments toward Memphis head coach Tubby Smith, his former coach, in a three-second clip. Lawson and his older brother, Dedric, announced their intention to transfer to play for the Jayhawks earlier this week.

“This is what we do when we leave Tubby,” Lawson said on the undated video, “(expletive) Tubby.”

Lawson expressed his dissatisfaction with his former school when he announced his intention to transfer earlier this month. Lawson quoted a song from Drake, which mentioned, “two middle fingers as I make an exit,” in a tweet that he later deleted.

“On behalf of my family and myself I would like to issue an apology to Coach Tubby Smith and Tiger Nation,” Lawson wrote Thursday night. “Despite my frustrations of this past year, my words and actions at the time were immature, thoughtless, and not becoming of who I am as a person or how my family raised me. Memphis will forever be my home and I wish Coach Tubby Smith and Tiger Nation the best moving forward.”

Lawson captioned his apologetic tweet: “This momentary (indiscretion) can jeopardize the most important thing in my life. I apologize for my inexcusable behavior.”

Lawson averaged 12.3 points and 8.1 rebounds for the Tigers this season in 33.7 minutes per game, earning American Athletic Conference Rookie of the Year honors.
