Who's ready for Deflategate: Round 2?

The New York Giants reported the Pittsburgh Steelers to the NFL last week after the Giants became suspicious the Steelers were playing with under-inflated footballs, FOX's Jay Glazer reports.

The Giants tested two of the Steelers' footballs after takeaways during the game and discovered them to be under weight.

The balls were sent to the NFL for further testing. The Giants are awaiting a ruling from the league.

The Steelers have denied any wrongdoing.
