The NFL have discovered that 11 of the 12 balls used by the New England Patriots in the AFC Championship game on Sunday were inflated at a level significantly below the leagues requirements, according to a report from ESPN.
The balls were reportedly fine when checked by officials before the game - which New England ended up winning 45-7 to book a place in the Super Bowl - meaning the alterations must have been made after that fact when the balls were given back to the Patriots.
'DeflateGate' as it has now come to be known has sent shock waves round the NFL, with social media ablaze with reaction from columnists, players and fans alike.
D'Qwell Jackson intercepted a Tom Brady pass during the game and he gave the ball to Colts head coach Chuck Pagano. Reports say that Pagano then gave the ball to Colts general manager Ryan Grigson who went to the league to complain.
It is to be seen if any punishment will be levelled against the Patriots, but this wouldn't be their first time they've been caught out. We previously had Spygate where a Patriots assistant was caught video taping the New York Jets defensive coaches signals during a game.
