Deshaun Watson just stepped foot on an NFL field for the first time in 700 days ... and the Houston Texans fans made their displeasure known -- letting the boo birds fly as he made his Cleveland Browns debut.
The 27-year-old quarterback is returning from an 11-game suspension for violating the league's personal conduct policy ... after dozens of massage therapists made sexual misconduct allegations against him.
Watson faced a hostile crowd as he made his Browns debut on Sunday ... with his former team's supporters heckling him as he lined up under center.
As we previously reported, attorney Tony Buzbee -- who repped almost every woman who accused Watson of sexual misconduct -- announced at least 10 of his clients would be in attendance for the game.
Watson's family was also at NRG Stadium to support ... with everyone wearing #4 jerseys in the stands.
Deshaun had a smile on his face prior to the Browns' first offensive drive ... but the television broadcast showed many fans were not happy to see him.
There may be a bit of rust for Watson, who hasn't played since 2020 -- the Browns ended up going 3-and-out in their first possession.
Watson was asked earlier this week about the potential response he'd receive in his first game back ... but he claimed his only focus was on his job as a leader of the team.
