Professional boxing career
Mercer turned pro in 1989 with a 3rd TKO of Jesse Hughes. He scored a series of knockouts and in August 1990 knocked down and outpointed big punching Smokin' Bert Cooper in a spectacular 12 round brawl that earned him Cooper's NABF title. In January 1991 he challenged undefeated Francesco Damiani for the WBO heavyweight title, scoring a one punch knockout victory in the 9th when behind on points. Later that year he beat undefeated puncher Tommy Morrison in five, and with a major world title fight on the horizon vacated his WBO belt and fought 42-year-old legend Larry Holmes rather than mandatory challenger Michael Moorer. It proved an unwise decision, as the crafty Holmes conned Mercer out of the fight, outjabbing the puzzled youngster and gaining both the points decision, and Mercer's world title fight with heavyweight king Evander Holyfield.

Having split fights with dangerous veteran Jesse Ferguson (Mercer was investigated for allegedly asking Ferguson to "throw the fight" during their first encounter), labored when overweight to a draw with trialhorse Marion Wilson, and seen a proposed 1994 bout in Hong Kong with Frank Bruno fall through, Mercer enjoyed an unexpected run of form in major fights, losing on points in a thrilling brawl with Holyfield in May 1995, losing a controversial decision in another wild punch up, this time with Lennox Lewis, in June 1996, and scoring a controversial points win over ex-champ Tim Witherspoon in yet another high action bout in December 1996. In the frame for a bout with Andrew Golota in 1997, Mercer suffered a neck injury and was out of action for 14 months. He returned February 1998 with a 2-round kayo of Leo Loiacono, but contracted Hepatitis B and was again inactive, this time for 20 months.

Comeback
In February 2001 a 39-year-old Mercer launched a final comeback, knocking out four journeymen before being matched with WBO title holder Wladimir Klitschko in a high-profile bout on HBO. Once famed for his incredible iron chin, Mercer looked his age and was knocked down in the first and stopped in the 6th. A brief dalliance in the mixed martial arts nixed a 2004 bout with DaVarryl Williamson, however he did return to boxing in 2005, now aged 44, but was stopped in seven by Shannon Briggs.

Kickboxing career
Continuing to seek a fighting career, Mercer opted to travel to Japan and challenged Musashi in the kickboxing combat sport K-1 on June 6, 2004. Mercer held a reasonable account of himself, but his age and inability to successfully defend kicks was evident as he went on to lose the bout via unanimous decision. On March 19, 2005, he had one more K-1 bout against Remy Bonjasky, to whom he lost via verbal submission, the first and only strike of the night, a head kick, would land on the square on the head of Mercer. It wasn't your typical fight; Mercer took one head kick and then quit in what was one of the most bizarre fights of all time as the kick didn't even seem to hurt him. As Mercer put it, "I got the shit kicked out of me". 

Mixed martial arts career
After a series of scheduled boxing matchups fell through (including a proposed bout against former champion Hasim Rahman), Mercer decided to try mixed martial arts (MMA) and approached Felix Martinez, co-founder of Cage Fury Fighting Championships, about working with the promotion. On March 21, 2007, Cage Fury announced that Mercer had signed to face underground street fighter and Internet legend Kimbo Slice at Atlantic City's Boardwalk Hall on June 23, 2007, as part of Cage Fury Fighting Championship 5. The bout was a non-sanctioned exhibition under the New Jersey Unified MMA rules.

Kimbo Slice won the fight in the first round with a guillotine choke submission.

Mercer later stated in the press conference at Adrenaline III: Bragging Rights when he was scheduled to fight Tim Sylvia under MMA rules instead of Boxing rules that he had expected Kimbo Slice to box with him and said that he did not really train in any other aspect of MMA and was unprepared for the guillotine choke.

On June 13, 2009, Mercer made a big splash when he defeated former UFC Heavyweight Champion Tim Sylvia at Adrenaline III: Bragging Rights. He won the fight via knockout in 9 seconds with a huge right hand to the chin, becoming the first man to ever defeat Sylvia by knockout.

In March 2010, it was announced that Mercer had signed with the King of the Cage organization.
