UAE Team Emirates-XRGs Adam Yates is suffering from a stomach illness at the 2026 Tour de France and his participation in the races final few stages is not guaranteed.The Briton dropped out the back of the peloton with 66km remaining on stage 17, and finished the days racing more than 26 minutes behind winner Jasper Philipsen.His shorts were stained with salt marks as he rode back to his team's bus, which he boarded as soon as he dismounted his bike. Yates is one of the key mountain domestiques for race leader Tadej Pogaar, and ordinarily would be providing crucial support on stage 19 and 20 which head into the high mountains and finish atop Alpe dHuez.But the 33-year-olds condition will have to improve significantly if he is to be of assistance to Pogaar.Yesterday he was really bad if it was a normal stage he wouldnt have finished, Pogaar said after stage 17. Luckily it was just a time trial and he managed it. He looked terrible.UAEs general manager Mauro Gianetti revealed that Yatess sickness began after Mondays rest day.Yesterday he was not feeling well and after the time trial he was really bad, vomiting, [and with a] stomach problem, Gianetti said. We said, OK, lets see what happens tomorrow morning, and he was feeling OK [this morning], not so bad like yesterday. He said, OK, Ill start. He was in the group and then one moment he spoke with Nils [Politt] and said, I will take the train [gruppetto] behind us to try to save some energy.This morning he was better but he was empty. With the full [gas] start, he suffered because he was empty from yesterday and only ate a bit this morning. He was really struggling. We knew it would be a hard day for him.Gianetti said that Yates has been isolated from the group, but expressed confidence that its nothing more than an episode. Neither was he concerned that the infection could be contagious to other members of the team.Its just him vomiting himself its just him, Gianetti said. Lets see if he can recover a little bit, [and] have some good food.Asked if Yates will start stage 18, Gianetti responded: I dont know. The doctors will decide.Pogaar seemed more confident than Gianetti that Yates would remain in the race. Today in the morning he looked a lot better, [he was] in a good mood and eating well. This was a good sign, but today was a hard stage even for me, and I think he paid a bit [the price] after yesterdays bad day.I think he will recover. Maybe not for tomorrow, but for Alpe dHuez. At least for the queen stage [on Saturday] he will be good.
