FORT WORTH, Texas -- TCU coach Gary Patterson on Tuesday apologized for his comments about officials and Oklahoma quarterback Baker Mayfield following Saturday's 52-46 loss to the Sooners.

After the game, Patterson criticized officials for several calls, including an intentional grounding penalty against Horned Frogs quarterback Kenny Hill on TCU's final possession. The officials initially ruled no penalty but later thew the flag after Oklahoma coach Bob Stoops argued that Hill was still in the pocket when he threw a pass, and that there were no receivers in the area.

Patterson also mentioned several plays where he believed Oklahoma held TCU, including on a second-quarter touchdown.

"You know, it's amazing, we can't say anything, but they can do whatever they want to," Patterson said Saturday. "So I don't really care right now if the commissioner, if they don't like what I think about what happened with the officials. We talk about sportsmanship in this game, and I've got a quarterback that writes a whole article on me, how I treated him wrong. But I can't talk about officials. Bottom line to it is, I wasn't happy with the officiating."

Patterson appeared to reference an ESPN The Magazine story published in August in which Mayfield's parents criticized TCU's handling of Mayfield's recruitment. TCU recruited Mayfield in high school but ultimately did not extend him a scholarship offer.

Patterson ended his news conference Tuesday by issuing an "apology" for his comments.

"When it came to officials, Baker, anything, the bottom line to it is you have to be bigger than all of it," Patterson said. "You have passion. I think in my 19 seasons here I can count on two hands, maybe six times that I've said things that usually by the next day I've regretted. After that, by the time I got to my radio show [I regretted it]. That's a good officiating crew. This game goes really fast. It's hard to be an officiating crew any more."

Patterson added that he wasn't prompted to apologize and had not spoken to Big 12 commissioner Bob Bowlsby about his postgame remarks.

"I have a high respect for Bob Stoops and the University of Oklahoma, [athletic director] Joe [Castiglione]," Patterson said. "Bob's a really good friend and I wish them the best. The bottom line is it's been great football games. So in this day and age right now in our horizon, everybody throws things out, everybody thinks they can say whatever they want to. The biggest thing for me is I don't want to be part of that. You go down and come back from 20 something points and you have some suspect things going on, but the bottom line is I've had some of those things go my way. You stay in this profession long enough you're going to have some things that are going to be good for you and some things that aren't."

Patterson ended by saying, "From a football coach, that's probably the closest to an apology as you'll ever get, probably."
