Missouri Tigers quarterback Maty Mauk was dismissed Thursday from the University’s football program, and shortly afterwards, Mauk shared a heartfelt, handwritten note regarding the dismissal on Twitter:

“It is with a heavy heart that I come to term with the fact that I will not be a part of this great University of Missouri Athletic organization. There are no words to describe my disappointment,” Mauk stated in the note. “While I cannot provide you with specifics about my future, there is one thing that I am very sure of–How incredibly thankful I am for the overwhelming support I have felt from the Athletic Department, the coaches, academics, my teammates, and most of all from the fans. I will and cannot tell you how much this support has meant to me and how thankful I am. Please know that my intent was never to bring any harm to the University or football program. I will continue to make myself the best I can be. I wish the Mizzou football program the best.”

Mizzou head coach Barry Odom explained in a statement that the decision to dismiss Mauk was a result of the QB’s “failure to live up to expectations in recent weeks.”

Missouri Tigers Quarterback Maty Mauk Posts Handwritten Note

The cause of all the uproar regarding Mauk’s inappropriate behavior in a video that went viral earlier in the week. In the video, Mauk appears to be snorting a line of white powder presumed to be cocaine. However, the video may in fact be a few years old, according to FOX Sports college football writer Bruce Feldman. 

Mauk had previously been suspended twice from the Tigers prior to his dismissal. He ended his career at Missouri with 4,373 passing yards, 42 touchdowns and 19 interceptions.

Maty Mauk‘s time at Mizzou hasn’t been what the quarterback imagined when he joined the Tigers. He spent his freshman year as a red shirt and lost out on the starting job, which he later claimed through injury, out of training camp.

He was finally named the starter for the 2014 season and was under center for all 14 games, but lost the job after four games of the 2015 season due to disciplinary reasons.

His career took another hit on Monday, when he was indefinitely suspended after a video surfaced showing a man, who is allegedly Mauk, snorting a white substance.

While it’s difficult to tell if the man is Mauk and what the powder actually is, Missouri isn’t taking any chances. They’ve officially suspended the quarterback during their investigation of the video.
