Hoffenheim lodged an appeal against Friday's Bundesliga result after losing the game to Stefan Kiessling's headed "goal," which was awarded despite clearly missing the target. The ball hit the outside of the net and rolled into the goal through a hole in the netting.
"I didn't really see it, I turned away but I was surprised to see the ball in. I didn't know how it got in," Kiessling said afterward.
The DFB said in a statement on Saturday that it will consult both teams, the referee, its control committee and football's governing body FIFA "to clarify the legal position for such cases internationally."
Hoffenheim wants a replay, as has happened before. In 1994, Thomas Helmer famously scored a "phantom goal" for Bayern Munich against Nuremberg, with his side winning the match 2-1. That game was replayed and Bayern won 5-0 to capture the title.
"We can all perfectly understand that such a 'phantom goal' is unjust," DFB vice-president Rainer Koch said. "The immediate call for a replay is understandable but we also know from the past that FIFA is very protective of a referee's decision."
