The 44-year-old Jones is a former four-weight world champion and is widely regarded as the best boxer of the 1990s, while 48-year-old Collins - the former WBO middleweight and super-middleweight champion - last fought back in 1997.
"I've spoken to Steve and I said 'I don't duck or dive nobody', so it's a very big possibility," said Jones.
"I wasn't looking for him but when he said he wanted to fight me I was like, 'OK'. I don't know where the animosity came from but if that's what he wants, he can get it.
"I said 'hey, I'm sorry it didn't happen when it should have happened, it wasn't because of me - but if that's what you want to do, I don't see no problem with it'."
Meanwhile, Collins, who beat British greats Nigel Benn and Chris Eubank twice each in his career, told Talksport: "It's a fight Roy Jones needs. He claims to be one of the greatest pound-for-pound fighters around but he refused to fight me.
"I was very happy with my career, but the one fight I wanted was Roy Jones, and when that didn't happen I retired. He was afraid of me. I don't think he's a coward, but at the time he was."
Collins has 36 wins from 39 professional fights, while Jones won world titles at middleweight, super-middleweight, light-heavyweight and heavyweight.
He became the first former middleweight world champion to win a world heavyweight crown in 106 years when he beat John Ruiz in 2003.
