Texas Tech thought it had already lived through enough QB drama. Turns out that another one just came up. Just hours before the Red Raiders were scheduled to meet Colorado in a major Week 5 Big 12 matchup, an eligibility mess landed on their doorstep. This time, it involved Thomas Castellanos, the veteran QB Joey McGuire brought in to stabilize its depth chart after the Brendan Sorsby situation blew up.

As On3’s Pete Nakos reported, the Kentucky Court of Appeals ruled Friday in favor of the NCAA. The ruling dissolved a temporary injunction that had allowed a group of Class of 2022 athletes to compete for a fifth season. Per reports, 38 athletes were affected by the ruling, including Thomas Castellanos. And just like that, Texas Tech had a decision to make.

The Red Raiders ultimately made a decision Friday afternoon. Thomas Castellanos will not be eligible to play against Colorado, according to Texas Tech, as reported by KCBD 11 and ESPN’s Pete Thamel. This is one more headache nobody needed after a very public situation with their former QB. 

Thomas Castellanos wasn’t brought to Lubbock to sit around and watch. He arrived late in the process after Brendan Sorsby’s departure left Texas Tech needing experienced insurance behind Will Hammond. The former UCF, Boston College, and Florida State QB had started 32 games during his college career and entered 2026 with plenty of big-game experience.

At Florida State in 2025, Thomas Castellanos threw for 2,760 yards and 15 touchdowns while adding 557 rushing yards and nine scores. He also helped the Seminoles stun Alabama in Week 1. That resume made him a pretty useful No. 2. He had already appeared in four games for Texas Tech, though his actual playing time was limited behind Will Hammond. 

His Red Raider debut came Sept. 12 at Oregon State. In three games in which he played, he accounted for four touchdowns, two through the air and two on the ground. Now he won’t be available when Texas Tech heads to Boulder.

The lawsuit originally claimed the NCAA unfairly excluded the 2022 high school class when introducing its new five-year playing rule. A local judge temporarily allowed the athletes to play, but the appeals court struck that down. Judges ruled the initial order lacked proper evidence, putting the NCAA’s standard eligibility limits right back in place.

The August lawsuit covered 38 athletes fighting for another season. Basketball players Seth Trimble and Mark Mitchell were among them, but neither had started his season yet. Thomas Castellanos had. He’d already played, already taken snaps, and then the ruling suddenly put his season in limbo. So it’s just bad timing for him.

While basketball players caught in the decision have time before their season starts, football players got hit mid-stream. Programs across the country are now forced to bench key fifth-year seniors instantly. Castellanos is just the most high-profile football starter to get pulled hours before game day.

Texas Tech had to make the football decision. And the school clearly wasn’t interested in testing the limits this time. After all, Colorado was already preparing for a Texas Tech offense with multiple QB possibilities in the mix.

Texas Tech is one option less against Colorado 

The NCAA’s five-for-five framework was supposed to simplify eligibility by giving athletes five school years to play five seasons, beginning with the 2026-27 academic year. But now, the transition has produced lawsuits, injunctions, and last-minute uncertainty. Thomas Castellanos is now caught right in the middle of it.

Colorado entered Saturday’s matchup as underdogs. Deion Sanders’ team prepared to hand the offense as backup to QB Isaac Wilson. Texas Tech, meanwhile, had been carrying Thomas Castellanos as an experienced option behind Will Hammond. Take him away, and the margin for error gets thinner for the starter.

Texas Tech has reportedly been evaluating options for Thomas Castellanos’ status beyond Saturday, according to Pete Thamel. So this may not necessarily be the end of his season. But for the Colorado game, the answer is settled. He won’t suit up. And that leaves the Red Raiders entering a big road game with one fewer QB option after spending much of the offseason trying to make sure they had enough of them.

Colorado and Texas Tech kick off Saturday at Folsom Field in Boulder. The legal drama may have arrived before kickoff, but its consequences are about to show up on the field.
