Dylan Groenewegen doubled up at the Tour de France as he won stage eight in Amiens, but Ireland's Dan Martin suffered a crash to cost a lot of time overall.
The Dutchman made it two wins in as many days following stage seven success in Chartres as he held off Andre Greipel and Fernando Gaviria at the end of this 181-kilometre stage from Dreux.
Mark Cavendish had been near the front as the race moved into the final 500 metres but could only manage 10th place.
Most of the general classification contenders crossed the line in the main bunch to hold station but UAE Team Emirates' Martin stood to lose over a minute after being caught in a crash inside the last 20km.
Dimension Data's Cavendish, seeking to reverse a frustrating first week of this Tour, was on the wheel of world champion Peter Sagan as the pack took a left-hander on to the finishing straight.
But he lost the wheel as Sagan launched his sprint early and could not find another opening.
Sagan would regret going as early as he did as he faded in the final 100 metres and finished fourth.
Martin later crossed the line as part of a group 75 seconds down.
The Irishman, winner of stage six on the Mur-de-Bretagne, was one of several riders to fall with 17km to go, with Quick-Step Floors' Julian Alaphilippe and Tom Skujins in the polka-dot jersey also caught out.
Martin, with blood pouring from his elbow, quickly set off in pursuit of the peloton with several team-mates to help.
They got within 30 seconds but as the paced ramped up at the front the gap soon began to grow again, leaving Martin to rue an expensive tumble.
BMC's Greg Van Avermaet retained the yellow jersey, and extended his lead by one second to seven over Team Sky's Geraint Thomas after nicking third place on the bonus sprint
