Groves was stopped in the eighth round of his IBF and WBA super-middleweight bout with Carl Froch at Wembley last month, but Sauerland is keen to keep the Londoner at the highest level with a fight in his home city.
Sauerland is quote by ESPN as saying: "George will box on September 13 or 20 and we are looking to get him out in London.
"He proved against Carl that he belonged at the world level and he was just punished for one mistake. The quickest way back for him to a world title via an eliminator which we are trying to arrange."
If Groves can win his comeback match, Sauerland is expected to try to secure him a shot at Sakio Bika's WBC belt.
