Lampley is convinced Mayweather allowed McGregor to win the first three rounds in a bid to make sure he could make more money with a second outing.
Mayweather pocketed a massive nine-figure sum when stopping McGregor on August 26, before riding off into the sunset with a 50-0 record.
Rumours ‘Money’ may be on his way back have already begun in earnest and Lampley believes Mayweather v McGregor II is firmly on the cards.
“Why should he retire? He created a marvelous scam with this whole thing,” Lampley told TMZ.
“He allowed Conor to quote ‘win’ 3 rounds so that the whole global MMA wish community could have something to latch on to.
“I think there’s a decent chance there’s enough suckers out there Floyd could maybe make another $150 million, why not?
“It’s all a set-up.”
Fans are already unhappy about McGregor’s skill in the boxing ring after forking out $99.95 to watch what was an easy win for Mayweather after those initial rounds.
Add to that the fact Mayweather revealed he hardly trained for the contest in the first place and it’s tough to see how a second clash could make it off the ground without some sort of rule change.
McGregor is a beast in the octagon, so other than Mayweather agreeing to fight MMA rules or allowing ‘The Notorious’ to use kicks, the former pound for pound king would struggle to reach the anywhere near the 4.4 million buys of the first contest.
