George Groves has signed a long-term promotional contract with Sauerland ahead of his much-anticipated rematch with Carl Froch at Wembley Stadium on May 31.

Groves, who has previously been promoted by Frank Warren and Eddie Hearn, joins former five-time world champion Mikkel Kessler and British heavyweight David Price at the German-based outfit.

The deal comes less than two weeks before Groves goes head to head against Froch for the WBA and IBF World Super Middleweight titles in front of an expected 80,000 crowd.

"I am extremely pleased to have signed with Team Sauerland," Groves said.

"I have boxed on their shows in the past and have known Kalle and Nisse (Sauerland) for years. The shows they put on in Europe are phenomenal.

"This is definitely a step in the right direction for me as I look to build my name not only across Europe but all around the world.

"I feel that now I have the right team in place to help me achieve everything I need to in boxing."

Groves has won 19 of his 20 professional bouts, with his sole defeat coming against Froch in November when the fight was controversially stopped in the ninth round.

The 26-year-old is also a former Commonwealth and British titleholder.

Kalle Sauerland said: "We are proud to have won the race for George's signature and look forward to guiding one of the most exciting talents on the planet.

"We are sure that George will write boxing history and delighted that we will be a part of the journey on a personal and business level."
