Video: Carl Froch shoves George Groves at Wembley press conference

The animosity between Carl Froch and George Groves remains as sour as ever after the super middleweight duo's press call at Wembley today.

While posing for photos pitchside at Wembley Stadium, where the fight will take place on May 31, Froch shoved London fighter Groves in the chest.

The duo were promoting tickets for the bout, with Groves saying on Twitter this afternoon that they sold out within an hour.

There was further confrontation during the press conference when Groves squared up to Froch's brother Lee.

The fight is a rematch of the pair's November clash, which Groves felt was stopped unfairly.

Watch the shoving incident, filmed by IFL.TV, at 2:35 in the video below.
