Superstar grey Logician suffered the first defeat of his career last Friday on the Knavesmire when finishing last of four in the Group Three Cumberland Lodge Stakes, but is said to have come out of the race with no problems.
The four year old grey was superb last term winning all five of his events with ease, including the Group Two Great Volitgeur at York's Ebor meeting and rounding of the season by landing the Group One St Leger at Doncaster.
Since that win the Khalid Abdullah owned horse had been off the track for almost a year, suffering a severely life threatening illness during the winter, that gave connections questions on whether he would ever race again.
Fortunately for the team he was back in action and better than ever in a two runner Conditions Stakes at Doncaster and having come out of the race in good health, Gosden and connections entered him in the Group Three event at York over the same course and distance he won on before in the Great Voltigeur.
However, this time around it was to his undoing as the colt seemed to lose his action in the soft conditions and when going for home found nothing and lost his six race unbeaten streak.
A post-race examination revealed no physical abnormalities connected to his performance, and trainer John Gosden was satisfied with how the son of Frankel went about his work on Tuesday morning.
Gosden said: "Logician seems fine and did one canter this morning. He just seemed to lose his action at York where it can get very wet on the Knavesmire and some horses just can't handle it.
"We've had him checked over since and he seems fine in himself. He moved well this morning but there are no decisions as regards future plans just now."
