The Saint has confirmed he will box unbeaten Scot Kenny Anderson on November 13th. Taking place at the M.E.N. Arena in Manchester, the fight will be chief support to David Haye's clash with Audley Harrison and screened live on Sky Box Office in 3D.
"We've got him. Kenny Anderson has signed", said Groves.
"It's going to be a defence of my Commonwealth title which I'm happy about and also, more importantly, it's going to be a final eliminator for the British title as well.
"Everyone's heard me moaning and whining about not being in the mix for the British title but now we've well and truly wedged our way in. So, providing I deliver the goods against Anderson, I'll be fighting the winner of that British title fight at the end of the year [between Paul Smith and James DeGale]."
Hard-hitting Anderson has won 12 from 12 as professional and landed a Commonwealth Games light-heavyweight gold medal in 2006 as an amateur. He also sparred Groves back in July ahead of The Saint's American debut in Las Vegas, but Groves places little significance on that time in the gym.
"He's mentioned the sparring saying we took this fight off the back of that sparring but we were talking about the fight long before we even sparred.
"That sparring we did, I know Kenny wasn't fit for it, and I was only 2 weeks into my preparations. He looked like he was holding back and I was working on different techniques so I don't read too much into the sparring. He better expect a lot better George Groves by the time we fight."
Groves had been scheduled to headline his own sold out show in London on Oct 30th but after his opponent James Obede Toney failed a medical, the show was cancelled and the Hammersmith man has instead landed a slot on the biggest British bill of the year.
"I'm so lucky to be boxing at the M.E.N. again, with it sold out. Last time when I got in the ring, there must have been a good 15,000 people in there and the reception was ecstatic.
"If I can get anything like that again, this is what you live for in Boxing, it's what you work hard for. I'm just chuffed."
The fight will be screened live on Sky Box Office from 8pm.
