It truly is an act of courage.

Oklahoma junior tight end Grant Calcaterra announced Thursday night on Twitter that he has retired from football due to concussions. After graduating from the University of Oklahoma in May with a degree in communications and a minor health and exercise science, he says he’ll move back to southern California to become a firefighter.

“Over a month ago, I received a concussion in practice,” Calcaterra said in an emotional video on Twitter. “What most of you may not know, is that I have had my fair share of concussions in my career. Ultimately, I came to the conclusion that it would best for me to step away from the game.”

“Football has been the biggest thrill in my life and it kills me to know it’s over.”

In his Oklahoma career, Calcaterra finished with 637 receiving yards and nine touchdowns. He’ll be remembered by Sooners fans for his one-handed, game-sealing touchdown catch against Texas in the 2018 Big 12 Championship.

To his teammates, coaches and friends, he’ll be remembered for much, much more as many took to Twitter to offer support in Calcaterra and his decision to step away.

Here are Oklahoma football players, coaches, alumni and others tweeting in support of the southern California native.
