Tinkoff-Saxo has lost a second rider in this year’s Vuelta following an incident involving a motorcycle on the race. This evening, the UCI WorldTour team has said it is considering whether it is safe to continue in the Spanish Grand Tour.

Sergio Paulinho needed 17 stitches after being hit by a moto on today’s Stage 11, according to a tweet from team owner Oleg Tinkoff.

Last week Peter Sagan abandoned the race after he was hit by a neutral service motorcycle.

In a statement published on its website this evening, Tinkoff-Saxo asked, "Can organisers of Vuelta a España guarantee a safe race?"

After providing details of the incident, it added: "Given the seriousness of the two accidents that involved riders of Tinkoff-Saxo at the Vuelta a España, the team will consider whether it is safe to continue racing under the current arrangements."

During the stage, TV footage showed riders angrily waving away motorbikes they believed had got too close.

The latest incident came just hours after Tinkoff-Saxo made public an open letter sent to the Vuelta's race director Javier Guillen and UCI president Brian Cookson outlining its concerns over Sagan's crash and demanding that measures be implemented to improve rider safety.

Among other things it asked that Vuelta organisers Unipublic "take appropriate and concrete measures to prevent similar incidents in the remaining stages of the race and its future events."
