"It was a great homecoming for my fans and I'm sorry I let them down. What went wrong tonight needs to and will be fixed. We're going to an immediate rematch and we look forward to returning the favor."
I hate rematch clauses. I can see it in certain cases but Julian Williams isn't the kind of fighter that I need to see fight someone twice in a row just because he lost.
He was a unified title holder, his manager should be fired if he didn’t have one in his contract. Especially for a voluntary defense
Williams needs to rematch him in September or December to recover from Brain Trauma and just box and move next time instead of going to war and taking chances. Coming back to soon without healing will get him stopped early and worse next time.
