Former Florida State quarterback Tommy Castellanos has entered the NCAA transfer portal, his agent Joe Hernandez of Just Win Management told ESPN's Pete Thamel.
Castellanos, a 32-game starter over his four years at Florida State, Boston College and UCF, is pursuing a fifth college season after he was granted a temporary restraining order by a Kentucky judge on Friday.
Texas Tech is one potential destination to watch for Castellanos, sources told Thamel, confirming a report by The Athletic.
The Red Raiders lost starting quarterback Brendan Sorsby this summer and could be in the market for another veteran passer to back up starter Will Hammond, who's coming back from a torn ACL suffered last October.
Castellanos started all 12 games in his lone season with the Seminoles in 2025, including their 31-17 upset victory over Alabama in last year's opener. He has produced 6,449 passing yards, 1,984 rushing yards and 72 total touchdowns over his career.
The 5-foot-9, 198-pound passer went undrafted in April and had a rookie minicamp tryout with the Miami Dolphins as a wide receiver in May. Castellanos had previously sought an NCAA waiver to be granted a fifth year of eligibility, citing his 2022 season at UCF in which he played in five games, with one coming in a conference title game before the NCAA changed its four-game redshirt rules.
Castellanos, 22, dropped his appeal in December to enter the draft.
He joined a growing number of college football players from the class of 2022 who are filing suit against the NCAA in an effort to return to college for a fifth year. More than a dozen former FBS players have entered the transfer portal this week after obtaining TROs.
Hammond is expected to be ready to start Texas Tech's season opener against Abilene Christian on Sept. 5 after recovering from his knee injury. The Red Raiders have an experienced backup in Tulsa transfer Kirk Francis behind him but were unable to add any additional transfers this summer following Sorsby's departure.
