Australian cyclist Rohan Dennis could bypass the men's road race to maximise his medal chances in the time trial.
The time trial specialist, a two-time world champion in the discipline, is one of the favourites for the July 28 event and one of Australian cycling's top medal prospects at the Tokyo Games.
While Dennis is entered in Saturday's road race on day one of the Games, he might sit out the 234km event.
Significantly, teammate Lucas Hamilton did not mention Dennis once when on Thursday discussing Australian prospects in the men's road race during a media call.
Richie Porte will be the Australian leader in the men's road race, with Hamilton and renowned domestique Luke Hamilton having key support roles.
"We obviously have myself and Richie as the climbers and then Luke Durbridge as the strong man," Hamilton said.
"We have to be careful with moves and groups that could go away - that will probably be my role.
"Richie is one of the best climbers.
"We have a lot of options there, with Durbo there to help us control the race."
While Dennis' absence would leave Australia a man down, he is a much better medal prospect for Australia in the time trial.
Most teams are also much smaller than usual in professional road cycling, with only Belgium, France, Italy and Spain having the maximum five starters in the field of about 130.
Dennis won the 2018 and '19 time trial world titles and was fifth last year behind Italian winner Filippo Ganna.
The Italian is not entered in the men's road race.
Dennis was on his way to a likely silver medal in the time trial at the Rio Olympics when a handlebar extension snapped, forcing a bike change that relegated him to fifth place.
