Anthony Joshua's pro debut Oct. 5

England's Anthony Joshua, who won the 2012 Olympic super heavyweight gold medal in front of the home fans in London, is going pro a year after his biggest amateur triumph.

The 23-year-old Joshua, who stands at an imposing 6-foot-6, has signed with Eddie Hearn's Matchroom Sport, Great Britain's top promoter. Joshua will be introduced at a news conference on Thursday in London, Hearn announced Tuesday.

Joshua is scheduled to make his professional debut in the headline bout -- likely a scheduled six-rounder -- on Oct. 5 at the O2 Arena in London.

Joshua joins Olympic teammates Luke Campbell, the bantamweight gold medalist who recently turned pro as a lightweight, and team captain Thomas Stalker, a junior welterweight, in the Matchroom Sport stable.

Joshua, who did not begin boxing until he was 18, also won a silver medal at the 2011 world amateur championships.

In the London Olympics, Joshua won all four of his bouts on the way to the gold medal. In the final, he faced reigning Olympic champion Roberto Cammarelle of Italy and won via disputed decision via count-back, an Olympic rule used when there is a tie and the scores of each judge are added together to determine the winner.
