British super middleweight rivals James DeGale (10-0, 8KOs) and George Groves (12-0, 10KOs) go face to face at a press conference to announce their long awaited showdown. Promoter Frank Warren stood back as both boxers exchanged heated words before an army of media members. DeGale-Groves will happen on May 21 at London’s O2 Arena as the co-feature to Nathan Cleverly’s clash with WBO light heavyweight champion Juergen Braehmer.
