A controversial trip to Milan for the Giro d’Italia, marred by rider safety protests and accusations of motorbike drafting, ended in typically chaotic fashion with the news that an Italian rider had been disqualified for headbutting and causing a rival to crash in the sprint for the line.

Sunday’s 15th stage of the Giro, a 156km route between Voghera and Milan, was won by Uno-X’s Fredrik Dversnes, the four-man breakaway surprisingly holding off the charging peloton at the end of the third fastest road stage in the history of the Italian race.

Seconds after Dversnes celebrated his first grand tour victory, the bunch sprint for fifth saw Jayco AlUla’s Bob Donaldson hit the deck, the Australian sprinter seen sporting a ripped skinsuit and some nasty road rash on his left side after the stage.

Footage of the incident showed Bardiani-CSF-7 Saber sprinter Enrico Zanoncello being pushed to the right during the sprint by Groupama-FDJ rider Paul Penhoët, as the riders battled for position. That contact forced the Italian to lean into Donaldson and appear to headbutt the 24-year-old, causing him to clatter to the deck.

After reviewing the footage, the race jury disqualified Zanoncello from the race, stating that his move represented a “deviation from the chosen line that endangers another rider (blow from the head)”.

The 28-year-old, who has two top tens to his name at this Giro, was also fined 500 Swiss Francs, docked 13 points in the points classification, and issued a yellow card. Normally, under the UCI’s disciplinary rules introduced in 2025, riders handed two yellow cards at a single race are immediately disqualified and banned from racing for seven days.

However, along with the yellow card, the Giro commissaires deemed it fit to boot Zanoncello off the race immediately.

Following the stage, Donaldson posted in a since-deleted Instagram story that he was “fine, sort of”, while Jayco AlUla confirmed on Monday morning that the 24-year-old will be able to start the race’s final week, having suffered some bruising to his skin.

Despite the intense, frenetic nature of bunch sprinting, instances of riders being disqualified for dangerous behaviour during races are few and far between, with Zanoncello’s expulsion reminiscent of Mark Renshaw’s disqualification at the 2010 Tour de France, when the key lead-out for Mark Cavendish was thrown off the French grand tour after headbutting Julian Dean.

Donaldson’s crash and Zanoncello’s subsequent disqualification brought a chaotic end to a controversial stage in Milan, dominated by a rider safety protest led by race leader Jonas Vingegaard.

After Vingegaard, Giulio Ciccone, and Filippo Ganna raised concerns with the organisers over the apparently dangerous nature of the city centre circuit around Milan, packed with fans, street furniture, and potholes, the jury decided, with around 35km to go, to neutralise the times for the general classification at the 15km mark, allowing the race for the stage victory to go ahead.

“We all thought the circuit was too dangerous. When we entered the circuit, we approached the jury president’s car to discuss it. We should be happy as riders because they listened to us,” pink jersey Vingegaard said after the stage.

Alongside cycling’s seemingly never-ending safety debate, the post-stage narrative was also dominated by accusations that the breakaway was unfairly aided by the drafting effect of a television motorbike travelling too closely to the escapees, enabling them to hold off the peloton at the end of a blisteringly fast day.

Both Lidl-Trek’s Max Walscheid and Unibet Rose Rockets’ Elmar Reinders – whose sprinters, Jonathan Milan and Dylan Groenewegen were denied the opportunity to break their Giro ducks – complained after the stage that the motorbike rider had influenced the outcome.

However, according to stage winner Dversnes, “the only motorbikes in the race were the guys in the breakaway”.

“The guys who said that motor pacing was involved also know that it is a known thing in the sport,” Dversnes said in his press conference. “Since it was not in their favour, they will of course complain about it.”
