“Forever living through big brudda,” Landon Hullaby, a defensive back at Texas Tech, posted on Twitter. “I love you so much and I got you and the family forever I swear get your rest King.”

Jaden Hullaby had been missing since Friday and a relative said Sunday on social media that the family couldn’t “track any of his devices.” He was reportedly last seen in his hometown of Dallas.

There is no word on a cause of death.

Hullaby played two games as a linebacker for Texas in 2020 and redshirted in 2021 before transferring to New Mexico.

“It’s such devastating and tragic news to hear of Jaden’s passing,” Texas coach Steve Sarkisian said in a statement. “He was a great person and someone we all enjoyed being around, coaching and spending time with. All of our thoughts are with his family, friends and teammates, and we want to send our deepest condolences to them in such a difficult time.”

Hullaby played running back and tight end for New Mexico last season and had 13 carries for 59 yards and caught two passes for 44 yards in eight games. He entered the transfer portal following the season.

“The Lobo family is saddened to learn of the passing of former RB/TE Jaden Hullaby,” New Mexico said on Twitter. “Our thoughts and prayers go out to Jaden’s family and all who knew him.”
