UCLA freshman tight end Jimmy Jaggers announced on Twitter on Monday that he was taking a medical retirement after being involved in a recent car accident that left him with a third concussion within the last year.

“I may no longer have the opportunity to play at the Rose Bowl,” Jaggers wrote, “but I will still be on scholarship and getting my degree. It was truly an honor being a part of something so special and I will miss the experiences, but know this is what’s best for me.”

Jaggers, a 6-foot-4, 255-pounder out of Roseville High in Northern California, was one of the most widely coveted tight end recruits. He did not play in his first season at UCLA.
