Promoter Eddie Hearn has confirmed Charlie Fitch will referee Carl Froch v George Groves II at Wembley on Saturday night.
Lengthy discussings, negotiations and objections over the official have been brought to an end after the IBF threw out a late objection from the Groves camp and confirmed Fitch would take charge.
The first fight between the two British super-middleweights was stopped controversially by Howard Foster Junior but Hearn remains confident there will be no repeat with the IBF and WBA titles again on the line.
The Matchroom boss had questioned the original choice of Jack Reiss and despite concerns also being raised over the suitability of Fitch, the 44-year-old from Brooklyn has landed the job.
Hearn told Sky Sports News: "There was another objection over the referee from Team Groves but the IBF made the decision last night that Charlie Fitch will referee the fight.
"The judges are now in place. No more dramas. Probably a few little mind games going back and forth but we're all set, the fight's on and we're ready to go.
"This fight is so close. It's a real 50-50 so any edge either fighter can get over his opponent is an advantage. You might be talking half a percent or a quarter but it doesn't really matter.
"George is fantastic at the mind games and he'll be doing more and more of that as time goes. Carl's kept himself very focus away from it but it's such a tight fight that all advantages will need to be exploited."
