HOUSTON (AP) - Houston Texans linebacker Tim Dobbins has been fined $30,000 for a helmet-to-helmet hit that gave Chicago's Jay Cutler a concussion.

The hit came in the second quarter of Houston's 13-6 win on Sunday night when Dobbins hit a scrambling Cutler after he threw a pass.

Cutler was past the line of scrimmage and called for an illegal forward pass on the play, and Dobbins was flagged for unnecessary roughness.

Cutler remained in the game for the rest of that series and threw an interception. He started experiencing symptoms at halftime and did not return.
