Oklahoma State safety Dylan Harding announced Friday that he is retiring from football after being diagnosed with spinal stenosis.
Harding, a junior, announced the news on Twitter late Friday night.
The 6-foot-2, 190-pounder wrote: "For everyone that hasn't seen or heard, I got diagnosed with spinal stenosis that's causing me to leave the game I've played since 2nd grade. I'll never forget the young days of watching Bedlam games with my pops and dreaming of being apart of something that special. Thankfully I got that opportunity and I'll never forget it. I just want to say thanks to all of my family, friends and people who have followed this dream of mine as it turned into a reality.
