Rolland is President of the World Rowing Federation (FISA) while de Vos holds the same position at the International Equestrian Federation (FEI).

This means that Sebastian Coe and Gianni Infantino, the respective heads of the International Association of Athletics Federations (IAAF) and football body FIFA, are expected to be overlooked once again.

Candidates for membership are drawn up by the IOC Programme Commission before being formally proposed by the ruling Executive Board.

They are then rubber-stamped at an IOC Session.

This final stage is due to take place in Lima between September 13 and 16.

It is possible that the Executive Board could delay their announcement until their meeting scheduled for between September 10 and 12, or it could be formally announced in August.

Rolland officially replaced IOC Executive Board candidate Denis Oswald as FISA President in July 2014.

The 49-year-old Frenchman claimed a coxless pairs Olympic rowing silver at Atlanta 1996 before winning gold four years later in Sydney.

If approved, he would become the third current French member of sport's most exclusive club alongside two other Olympic gold medallists in Montreal 1976 110 metres hurdles winner Guy Drut and three-time slalom canoeing champion turned IOC Athletes' Commission vice-chair Tony Estanguet. 

It comes with Paris widely expected to be confirmed as host of the 2024 Olympic and Paralympic Games during the same Lima Session.

De Vos, meanwhile, was elected to replace Princess Haya Bint Al Hussein in December 2014 as FEI President after serving three years as secretary general.

The 53-year-old spent the previous two decades working in equine roles including at the Belgian Equestrian Federation.

He would become the European nation's second current member of the IOC after Baron Pierre-Olivier Beckers-Vieujant.

A maximum of 15 IOC members at any one time directly represent the IFs.

Thirteen of these positions will be filled if Rolland and de Vos are approved.

Coe and Infantino were both also overlooked for IOC membership last year, when Italy's International Bobsleigh and Skeleton Federation President Ivo Ferriani was appointed as the only new IF representative.

IOC President Thomas Bach said then that four places were still free for IF Presidents, adding that "we wanted to wait until we had a full picture". 

It is therefore possible that Coe and Infantino could still be added this year, although there has been no indication that this will happen.

Infantino was elected FIFA boss to replace the disgraced Sepp Blatter in February 2016.

Coe replaced Lamine Diack as IAAF head in August 2015, shortly before his predecessor was implicated in a scandal which included the alleged covering up of Russian doping cases.

The Briton, who spoke alongside Bach as a fellow athlete representative at the 1981 Baden-Baden Congress, presided over the suspension of the Russian Athletics Federation later in 2015.

This deviated from the IOC policy, championed by Bach, which allowed Russians to compete at last year's Rio Olympic Games under their own flag so long as they fulfilled specific eligibility criteria.

Other IF Presidents to have been overlooked for IOC membership include International Judo Federation boss Marius Vizer.

He publicly criticised Bach at the 2015 SportAccord Convention in Sochi before being swiftly maneuvered out of his position as SportAccord President.

The IOC will not confirm the list of candidates for membership or the number of appointments due to be proposed.

“We cannot confirm any names but we can tell you that the candidates for IOC membership coming from the International Federations are always chosen in close consultation with Association of Summer Olympic International Federations and Association of Olympic Winter International Federations and NOC representatives are chosen in close consultation with [the] Association of National Olympic Committees," a spokesperson said.

National Olympic Committee and individual representatives are also expected to be named this year. 

There are currently 95 IOC members, although one - Ireland's Patrick Hickey - remains temporarily self-suspended following his arrest on ticketing charges at Rio 2016.

This remains 20 short of the maximum ceiling of 115.
