“In this business, you see a lot of things. You share the wins, the losses, the laughs, the cries…and so on. Nothing prepares you for the loss of life. We lost a good one. Rest easy big man!” Creel said on Twitter.

Yarbrough was a defensive lineman at OBU, a Division II program in Arkadelphia, Arkansas. He played in Thursday’s 42-32 win at Oklahoma Baptist, tallying two tackles.

His mother, Mattie Yarbrough, told WFAA from her home in Rowlett that she had just seen her son when she traveled to Oklahoma to watch him play on Thursday night.

“Had a big hug, took pictures, took videos – I loved on him as I always do after every game,” she said. “His mama is his biggest fan.”

“He was my buddy. He was my baby,” she added.

Yarbrough was a sports management major on track to graduate from OBU in May 2023. He hoped to become a graduate assistant with OBU’s football team.

He was an All-Great American Conference honorable mention last season after totaling 27 tackles, including 1.5 for loss, while playing all 11 games for the team.

He also played eight games as a freshman in 2019, while the 2020 season was canceled due to COVID-19.

Ouachita Baptist is scheduled to play its second game of the season on Saturday against Southern Nazarene.

The university will share more information this week on funeral arrangements for Yarbrough and other campus gatherings to celebrate his life.
