"The Medical Picture Is Unambiguous" — Lidl-Trek Confirm Juan Ayuso Will Miss The Full Ardennes Trio After Post-Itzulia Blood Work Returns Evidence Of A Recent Viral Infection, Handing Mattias Skjelmose Undiluted Amstel-Flèche-Liège Leadership
Lidl-Trek issued a Friday-evening press release from their Sittard Ardennes base confirming that Juan Ayuso will not start any of the three Ardennes Classics. The 23-year-old Spaniard — who withdrew from Stage 4 of Itzulia Basque Country on 9 April citing stomach issues after being dropped on the Elorritxueta on the queen stage — returned blood work on Wednesday afternoon showing elevated markers consistent with a recent viral infection. Team doctor Emanuele Guarneri's Friday-morning review ruled Ayuso out of Amstel Gold Race on Sunday, La Flèche Wallonne on 22 April and Liège-Bastogne-Liège on 26 April. The rider has returned to his Andorra base for a minimum fourteen-day recovery window.
Ayuso's 2026 spring has been the kind of compounded setback that transfer windows were designed to erase. He crashed out of Paris-Nice while in the race lead on 15 March. He spent ten days off the bike with a knee contusion. He returned at Itzulia as the designated GC leader, then was dropped on the queen stage, then withdrew the following day. "I ran faster to the bathroom than the stage itself," Ayuso told reporters at the Itzulia hotel on Thursday in a line that summed up the Spaniard's view of a spring that has not come together since his mid-January training block. Lidl-Trek had held back on the Ardennes confirmation until the Wednesday blood work could be reviewed — the Friday announcement makes the absence official.
The immediate tactical consequence is that Mattias Skjelmose steps up to full and undiluted Ardennes leadership across the three-race block. The 25-year-old Dane — defending champion at Amstel Gold Race after his April contract extension through 2028 — will be the single protected rider on Sunday in Valkenburg. Giulio Ciccone is confirmed as the second option at Amstel, then becomes the outright leader at Flèche Wallonne on the Mur de Huy where his short-punch climbing profile matches the finish. At Liège, Skjelmose and Ciccone line up as co-leaders in a race where the Dane's 2025 second-place finish behind Pogačar is still the team's best recent La Doyenne result.
DS Steven de Jongh's Friday-evening briefing at the team hotel in Maastricht was clear. "We have one protected leader at Amstel and that is Mattias. We have one protected leader at Flèche and that is Giulio. At Liège, we ride with two cards — Mattias for the long-range move, Giulio for the Mur-Saint-Nicolas punch." The eight-rider Amstel squad around Skjelmose is confirmed as Ciccone, Bauke Mollema, Tim Declercq, Daan Hoole, Otto Vergaerde, Jasper Stuyven and Toms Skujiņš. The final pre-race Sittard training recon is scheduled for Saturday morning on the Cauberg and the Geulhemmerberg sectors.
The absence also reshapes the betting markets. Skjelmose had been 8/1 for Amstel Gold behind Evenepoel at 5/2. The Dane's price has shortened to 9/2 on Friday afternoon with the UK bookmakers, displacing Matteo Jorgenson as the second favourite. The Cauberg-finish formula that gave Skjelmose the 2025 win — a 20-second gap coming off the Cauberg with two kilometres to go, held to the line — is precisely the profile the Dane's 2026 form curve suggests he can repeat. Lidl-Trek's team bus footage from the Thursday Valkenburg recon shows Skjelmose putting down numbers on the Cauberg that team analysts describe as "the best of his career."
Ayuso's own season is now re-anchored around the summer. His Lidl-Trek contract, signed in October 2025 after his UAE Team Emirates-XRG exit, is structured around a Tour de France co-leadership with Skjelmose. The 23-year-old has fourteen weeks to recover and prepare for a Critérium du Dauphiné pre-Tour block that will be his first proper GC test since the autumn of 2025. Team manager Luca Guercilena's Friday-evening radio interview with Belgian television framed the missed Ardennes as "disappointing but not existential. The Tour is the season, not Amstel. Juan will be on the Col du Tourmalet in July."
The wider 2026 spring injury and illness toll continues to be the defining narrative of the Classics campaign. Ben Healy's fractured sacrum from the same Itzulia week has ruled the Irishman out of the Ardennes. Tom Pidcock's knee contusion remains under assessment. Kim Le Court-Pienaar's fractured wrist from the Tour of Flanders crash rules out the defending Liège Femmes champion. Lidl-Trek's next medical update on Ayuso is scheduled for 2 May — the Friday after Liège — with a target return at the Tour de Romandie or the Critérium du Dauphiné still subject to the viral infection resolving cleanly over the next fortnight.
