Browns rookie Zane Gonzalez forced overtime by kicking a season-long 54-yard field goal with 47 seconds left in regulation to tie it 9-9.
The Browns (0-7) committed 12 penalties and dropped to 1-22 in two seasons under coach Hue Jackson. Their troubles worsened as Thomas, a 10-time Pro Bowler, missed his first play in 11 seasons.
