The New England Patriots have extended their lead over the Pittsburgh Steelers.
Stephen Gostkowski's 47-yard field goal gave the Patriots a 20-9 lead with a little less than 10 minutes to go in the third quarter.
Pittsburgh thought it has produced a turnover when New England quarterback Tom Brady appeared to fumble during a quarterback sneak. The officials ruled no fumble and Steelers coach Mike Tomlin challenged the call. Officials said the call on the field stood, meaning there wasn't enough evidence to overturn it.
