Promoter Eddie Hearn felt Tyson Fury was "very lucky" to avoid his fight being stopped last Saturday night at the T-Mobile Arena in Las Vegas.
He won a twelve round unanimous decision over heavy underdog Otto Wallin. If the fight would have been stopped, Wallin would have been awarded a TKO win - since the cut was caused by a punch.
Fury suffered a severe cut above his right eye in the third round and it was bleeding heavy for most of the fight, and he also suffered another bad cut on his eyelid. The cuts required nearly 50 stitches to close.
A loss would have derailed Fury's February rematch with WBC heavyweight champion Deonay Wilder.
The cut will take several months to heal.
Hearn expects Fury to be a better, more focused fighter if he steps in the ring with Wilder on a date in February.
"I haven't seen it, because I was on a plane, but I landed and checked my social media and saw the scores and saw the cut," Hearn told Sky Sports. "I think firstly he's very lucky not to lose the fight with that cut.
"I think any other country in the world, they would have stopped the fight. I just think in those fights against that opposition sometimes you don't get yourself motivated to perform and obviously he didn't perform at his best, but he had the injury as well and I think you'll see him perform a lot better against the likes of Wilder and stuff like that.
"I don't know how long he's going to be out for. I don't think he'll be ready for his February fight, but I don't think Wilder will be ready for the February fight either, so it might work in their favour. I expect a different Tyson Fury against Wilder, if that rematch gets made."
