Ali/Clay hit the canvas 4 times. The only men who achieved this were Sonny Banks, Henry Cooper, Joe Frazier and Chuck Wepner.
Ali was never counted out in his career.
however , most experts agree the wepner knock down was an erroneous call by referee tony Perez as wepner actually pushed ali as he was standing on Ali's foot and ali went down.
However no rule in boxing against stepping on a foot, it was not a push but a punch. I was there and saw it first hand.

Leon Spinks was knocked down a total of 7 times throughout his professional boxing career. Notably, he was knocked down in his famous fight against Muhammad Ali in 1978, which he won to become the heavyweight champion. Spinks's resilience was evident as he often managed to recover and continue fighting despite being knocked down.
