Chris Algieri looks back on past challenges in boxing

Which one of your victories taught you the most about overcoming obstacles inside the ring?

"My 10th pro bout against Julius Edmonds. I went into the fight with a sore right hand and then broke my left hand in the 2nd round. Finding a way to win has always been a major part of my style and strategy. I didn't even tell my coaches I was injured until after the fight. I finished the fight with a 4th round KO and that truly was one of the biggest obstacles if not the biggest I have ever had to overcome.

"And let's not forget in my most previous fight against Ruslan Provodnikov. I made a mistake in the first round and I paid for it. I was forced to pay the price and fight the remainder of the fight with a badly swollen eye. But, I still found a way to win. Sticking to the game plan, and staying focused in times of adversity, that's what separates me from other fighters. My mental make-up and my mental strength has always been the difference in my fights, and that is what will propel me once again to victory on November 22nd."
