Watson told team doctors he felt pain in his throwing shoulder, following Sunday’s dramatic 33-31 come-from-behind victory over the Baltimore Ravens.
Watson arrived in Cleveland ahead of last season following his trade from the Houston Texans, which was prompted by a slew of sexual misconduct allegations against the star signal caller.
The Browns are off to a surprising 6-3 start, riding one of the most stingy defensive units in football.
Cleveland’s defense is allowing an NFL-best 242.7 yards per game. The team’s scoring defense, 18.9 points per game, sixth best.
Watson, 28, has yet to put up the dazzling numbers in Cleveland that he posted in Houston.
In his last season leading the Texans in 2020, Watson threw for a league-high 4,823 yards in 16 games, to go along with 33 TDs and just 7 interceptions.
In his 12-game Browns career, Watson has thrown for a modest 2,217 yards, 14 touchdowns and 9 picks.
Backup Browns QB P.J. Walker has started three games this year, helping Cleveland to victories over the Indianapolis Colts and San Francisco 49ers.
