Texas Tech Signs Castellanos to Address QB Depth Amid Eligibility Legal Battles

Key points

• Thomas Castellanos, a former Florida State quarterback, has committed to Texas Tech via the transfer portal.
• The move follows a temporary restraining order granted in Kentucky, allowing Castellanos a fifth year of eligibility.
• Texas Tech lost its top transfer portal target, Brendan Sorsby, who stepped away due to a gambling addiction.
• Castellanos is expected to serve as a backup to starting quarterback Will Hammond, who is recovering from a torn ACL.
• The Big 12 confirmed Castellanos remains eligible despite new rules barring former professional athletes, as he attended an NFL minicamp without signing a contract.
• Castellanos previously led Florida State to a Week 1 upset against Alabama and posted 2,760 passing yards and 15 touchdowns in 2025.

Background

This development occurs amid a broader legal struggle over NCAA eligibility rules. In late August 2026, a Kentucky judge granted temporary injunctions to Castellanos and basketball player Mark Mitchell, allowing them to pursue additional eligibility years. This followed the NCAA’s implementation of age-based eligibility restrictions, which sparked multiple lawsuits. Additionally, power conferences like the Big Ten and SEC recently enacted bans on former NFL players returning to college, creating a complex regulatory environment for athletes like Castellanos who have interacted with professional teams.

How outlets are covering it

On3 emphasizes the practical impact on Texas Tech’s roster, noting that Castellanos provides crucial depth after the departure of Brendan Sorsby and the injury to Will Hammond. The outlet also highlights that Castellanos’s agent indicated he is open to playing wide receiver. CBS Sports focuses on the regulatory aspect, confirming that the Big 12’s new ban on professional athletes does not affect Castellanos because he did not sign a contract with the Miami Dolphins. While both outlets agree on the commitment, On3 frames it as a solution to a depth crisis, whereas CBS Sports frames it as a victory in the ongoing eligibility legal battles.

Why it matters

Castellanos’s commitment illustrates the intersection of legal challenges and roster management in college football. For Texas Tech, it mitigates the risk associated with Will Hammond’s injury. For the broader sport, it demonstrates how court-ordered injunctions can override conference and NCAA rules, potentially setting precedents for other athletes seeking additional eligibility. The situation also underscores the volatility of the transfer portal, where top targets can drop out due to personal issues, forcing programs to pivot quickly.

What to watch

Texas Tech will open its season on September 5 against Abilene Christian, followed by a Week 2 match against Oregon State. The team will begin Big 12 play in Week 3 against Houston. The outcome of the underlying eligibility lawsuits and the enforcement of conference bans on former professional athletes will likely determine the long-term status of players like Castellanos and others in similar situations.
