Heavyweight contender Chris "The Nightmare" Arreola (38-6-1, 33 KOs) has yet to make a decision regarding his future in the sport.

On Saturday night at the Barclays Center in Brooklyn, he lost a hard-fought twelve round unanimous decision to undefeated rising star Adam Kownacki (20-0, 15 KOs).

The fight with Kownacki set the CompuBox heavyweight record for combined punches landed and thrown in a heavyweight fight. They landed a combined 667 punches, besting the previous record of 650, while throwing 2,172 punches, far surpassing the previous mark of 1,730.

Arreola tried his best to fight Kownacki off, but the Polish boxer continued to come forward and throw punches all night.

"Adam is relentless," said Arreola. "He just keeps coming. I know I got him with some good punches and he got me with some good ones. I was more than ready to go all 12, but Adam came in and won the fight."

After the punches continued to fly through the last bell, the two heavyweights embraced in the ring prior to hearing the judges' scores. After 12 rounds, all three judges saw the fight in favor of Kownacki, by scores of 117-11 twice and 118-110.

Prior to the fight, Arreola told reporters that he was likely going to retire in the event of a loss.

But after such a performance, Arreola is going to evaluate that position with his family and friends, and then he plans to make a final decision.

"Retirement is something I need to talk to my family and team about," said Arreola. "I gave it my all this fight. I let it all hang out. After breaking my hand, I kept fighting because I believed I could win."
