The Browns finally scored on Szmyt's 48-yard field goal in the third quarter. Baltimore still led 10-3 when Carson Schwesinger forced Henry to fumble and Tyson Campbell recovered at the Ravens' 35.
That field position changed Cleveland's task. The Browns needed seven plays to cover the distance, with Audric Estime scoring on a 2-yard run to tie it with 8:33 remaining. Estime had been signed from Minnesota's practice squad during the week while Cleveland dealt with Quinshon Judkins' ankle injury.
Two empty possessions leave the game exposed
Szmyt missed another 48-yard try later in the fourth quarter. Baltimore could not take advantage: its final two possessions failed to produce a first down. Cleveland got the ball at its 20 with 1:59 left, and Watson found Jerry Jeudy for a 33-yard gain on the winning drive.
The Ravens briefly appeared to have survived when Szmyt's 42-yard attempt was blocked. The offside flag made it no play, however, and his next kick went through from five yards closer.
Huntley, filling in for Lamar Jackson while Jackson remained out with an ankle injury, completed 19 of 31 passes for 165 yards and a touchdown. Henry finished with 58 yards on 17 carries. Baltimore hosts Cincinnati next Sunday after a divisional loss in which its opening 10 points had to last the entire game.
