Germany's Thomas Bach is likely to announce his candidature for president of International Olympic Committee to succeed Jacques Rogge.
Bach, 58, won a team foil gold in the 1976 Olympic fencing event. The German lawyer and IOC vice president is also head of the German Olympic Sports Confederation, or DOSB, reports Xinhua.
As chairman of the IOC juridical commission, he leads most of the investigations into doping cases.
There are other possible candidates that include another IOC vice president Ng Ser Miang of Singapore and Richard Carrion, head of the IOC's finance and audit commissions from Puerto Rico.
Ng led the organising committee for the inaugural Youth Olympics in Singapore in 2010. Carrion secured a record $4.38 billion deal with NBC for U.S. TV rights through 2020.
Rogge who succeeded Juan Antonio Samaranch in 2001, steps down as president on Sept 10 after 12 years as head of the IOC.
The deadline for declaration of candidacies is not until June 10, three months before the vote in Buenos Aires, Argentina.
