The NFL fined linebacker Tim Dobbins $30k for his hit on Jay Cutler last Sunday.
Cutler left the game after completing 7-of-14 passes for 40 yards and rushing three times for 37 yards. The Bears fell to the Texans, 13-6, which snapped Chicago's six-game winning streak.
Jason Campbell was 11-of-19 passing for 94 yards and rushed once for five yards in place of Cutler on Sunday.
Cutler is completing 59.2 percent of his passes this season and has thrown for 1,814 yards and 12 touchdowns. The concussion is the sixth of his career.
