According to promoter Tom Loeffler of K2 Promotions, former world champion Wladimir Klitschko is "50-50" on whether or not he intends to exercise an immediate rematch with IBF, IBO, WBA champion Anthony Joshua.
Back in April, before a record crowd of 90,000 fans at Wembley in London, Joshua recovered from a sixth round knockdown to rally down the stretch and stop Klitschko in the eleventh round to unify the three belts.
Now Klitschko has the option of getting an immediate shot at revenge - if he chooses to go in that direction.
The fight with Joshua was Klitschko's first bout since November 2015, when he suffered a shocking twelve round decision loss to Tyson Fury.
Klitschko, 41-years-old, may ride off into the sunset or take one final fight to finish off a Hall of Fame career.
Loeffler told Sky Sports News HQ: "Wladimir hasn't made a decision. If he retires on that fight, he had such a great run in the heavyweight division there'll be no better way to go out. That was just a tremendous fight
"I really think it's 50-50. Every time I talk to him it's almost like he's torn both ways. We'll naturally support him either way he decides. If he decides to take the rematch that's one the fans will look forward to."
If Klitschko decides to go in another direction, there is already a Plan B - where Joshua would make his mandatory title defense against Kubrat Pulev of Bulgaria - who already has been stipulated in to fight the winner of Joshua-Klitschko.
The IBF has given Joshua permission to do the Klitschko rematch, but it must be done by December 2nd or the Pulev defense will be the only option. If he fails to make the mandatory against Pulev, the sanctioning body will then move forward with stripping Joshua of his title.
