HOUSTON -- Quarterback Deshaun Watson has requested a trade from the Houston Texans, league sources told ESPN's Adam Schefter on Thursday.

Watson made the request to the team weeks ago, sources told ESPN.

The Texans' new head coaching hire, David Culley, has not and will not alter Watson's thinking, sources told ESPN.

Watson hasn't spoken to new Texans general manager Nick Caserio or executive Jack Easterby, sources told ESPN.

Watson, who signed a four-year, $156 million contract extension in September, is under contract through the 2025 season. He has a no-trade inclusion in his contract, but given the length of his contract and the possibility of franchise-tagging him for three years, the Texans could choose not to trade him and would have control of his rights through the 2028 season.

The trade request comes after Watson was reportedly unhappy with the process used by the team to hire Caserio in early January.

After Watson signed his contract extension last year, he was emotional as he discussed how happy he was to commit to the franchise and the city.

"It's just an amazing moment for me to be able to extend my career in a location, in a place, in a home, I would say, that my family loves, that I love," Watson said in September. "I want to continue to dive into the community most of all and just continue to build my legacy, just build our legacy as a whole and do something that we've never done before."

Watson set career-highs this past season in passing yards, touchdowns and completion percentage. He also threw a career-low seven interceptions. His 33 touchdowns and 4,823 passing yards were also single-season franchise records.

The quarterback's best individual season came in a season where the team went 4-12 and fired head coach and general manager Bill O'Brien after an 0-4 start.

Although he has played only four seasons (54 games), Watson's 104 passing touchdowns and 14,539 passing yards rank second in Texans franchise history behind Matt Schaub (124 touchdowns and 23,221 passing yards in 90 games).

Watson is currently the NFL's all-time leader in completion percentage behind New Orleans Saints quarterback Drew Brees. In 2020, he became just the 11th player in NFL history to complete at least 70% of his passes in a single season.
