Turns out that little dance in the end zone Monday night cost the Chiefs more than a penalty.

The NFL fined the Chiefs' Justin Houston $7,875 for unsportsmanlike conduct when he began that group celebration in the end zone following his fumble return for a score against the Steelers in Pittsburgh. That play was reviewed and ruled an incomplete pass and the Chiefs drew the unsportsmanlike conduct penalty. Pittsburgh won 16-13 in overtime.

Linebacker Tamba Hali was fined $25,000 by the NFL for striking Steelers quarterback Byron Leftwich with his helmet.
