Rabobank's Lars Boom has tightened his grip on the leader's gold jersey by winning stage six of the Tour of Britain, from Taunton to Wells.
Dutchman Boom now leads the general classification by 28 seconds from Team NetApp's Leopold Koenig.
Britain's Geraint Thomas was involved in a crash that eventually saw him finish the stage in 25th place and slip down to 12th overall.
Ian Bibby's tour ended after the same crash, having broken his collar bone.
Bibby, who rides for the Motorpoint team, was taken in an ambulance to hospital after the crash which involved several riders.
Boom edged out Frenchman Alexandre Pichot of Team Europcar and Koenig in a sprint finish after a demanding 90.7 mile (146 km) stage.
It was the second stage win of the race for Boom, who is now well placed with only this weekend's final two stages remaining.
Britain's Daniel Lloyd is third in general classification, one second behind Koenig.
Team Sky's Sport director Sean Yates said of the Thomas crash, ""That wasn't in the plan. G [Geraint] is a bit cut up after his crash but he is okay.
"He was going for the first sprint at kilometre 12. We knew it was going to be a fast one and they were going for it so not a good time to hit the deck.
"It was lucky I guess that it wasn't a lot worse given the speed. When you hit the ground going almost 70km an hour you can do a lot of damage."
