Esteban Chaves retained the race leader's red jersey on an eighth stage of the Vuelta a Espana which saw Dan Martin's chances ended in a crash.
Jasper Stuyven (Trek) won the 182.5-kilometres route from Puebla de Don Fadrique to Murcia, which included a large crash which forced the withdrawals of Martin (Cannondale-Garmin), Tejay van Garderen (BMC Racing) and Nacer Bouhanni (Cofidis). Martin had been third entering the day.
A collision with a neutral service vehicle with around 10km to go ruled Peter Sagan (Tinkoff-Saxo) out of contention and Stuyven won a sprint ahead of Peio Bilbao (Caja Rural) and Kevin Reza (FDJ).
Chaves (Orica-GreenEdge) finished 12th and Chris Froome (Team Sky) was also safely in the pack, in 27th place.
Kris Boeckmans was also involved in the day's main crash and taken to a hospital.
His Lotto-Soudal team said: "The 28-year-old rider has a severe facial trauma with several fractures, he'll probably need surgery.
"Boeckmans also has a concussion, three broken ribs and had a bleeding in his lung. The doctors will now keep him in an induced coma for a few days."
