Terrible news for Deshaun Watson -- just months after tearing his Achilles, the Cleveland Browns quarterback ruptured his tendon again ... and his football future is now up in the air.
The development was reported minutes ago ... with insiders saying he underwent tests on Thursday that showed the controversial signal-caller re-injured the tear he suffered during the Browns' matchup against the Cincinnati Bengals in October.
Watson is now in jeopardy of missing the entire 2025 season ... meaning Cleveland is in need of a quarterback more than ever.
