LONDON -- Derek Chisora was cryptic when it came to his boxing future but admitted "when it's time, it's time" to step away from the sport after defeat to Deontay Wilder on Saturday.
Chisora (36-14, 23 KOs) lost a split decision to Wilder (45-4-1, 43 KOs) in his 50th professional fight.
The Brit has long insisted it would be his last despite speculation a win could see him enticed back for one more fight. Despite the loss, Chisora didn't categorically say he would retire but said it was "time."
"You know what, I don't know. God's honest truth I don't know," Chisora said when asked if, as he sat there, he wanted to fight again.
However, he appeared more decisive later in the news conference.
"To be honest with you, I'm tired now. I can't do it anymore. You know when it's time, it's time.
"I've had a great career."
Chisora said he thought he beat Wilder and wasn't happy with the second knockdown when he fell through the ropes in Round 11.
"No, I didn't," Chisora said when asked if he agreed with the scorecards.
"The ropes were very loose. I went on the ropes, he fell in me, the ref said break ... I went through the ropes, they started counting. The second time they took a point but still counted me out and I don't understand why."
