The Briton Geraint Thomas has retired from the time trial of the World Road Championship, saying that he is not in "good shape to perform at his best".
The 2018 Tour de France winner continues to plan to compete in the Yorkshire road race, which starts on Sunday.
"I tried to get back into shape after my break after the tour," said Thomas.
"The decision was made … to skip the time trial and sign the team for the road race."
The Men's Time Trial will take place on Wednesday with the Men's Road Race on Sunday, the 29th of September, the last day of the event.
Thomas, 33, was knocked down to second place at this year's Tour de France by Ineos team-mate Egan Bernal, who will not compete in Yorkshire.
"Although it is a shame that Geraint is retiring from the time trial, we understand and support his decision," said Stephen Park, Performance Director of British Cycling.
John Archibald, who finished second in the time trial of the men's elite at the National Road Championships, will replace Thomas in the time trial.
