Ex-champion Dumoulin pulls out of Giro d'Italia

Terracina - Former Giro d'Italia winner Tom Dumoulin pulled out of this year's race early on in Wednesday's fifth stage because of a knee injury sustained in a mass fall during the previous stage.

The Sunweb rider signed in and embarked on the fifth stage, which got underway under driving rain at Frascati, but once he starting pedalling the Dutch rider decided he could not continue.

Dumoulin, who won in 2017 and was second last year behind Britain's Chris Froome, had earlier insisted he would tough out the race.

"Knee still hurts but we hope it will get better through the day. Will give everything I have to make it. Fingers crossed," the Dutch rider wrote.

The fifth stage, a short 140km run from Frascati, just south of Rome, to Terracina, will be mostly raced under the rain, with a 1.5km home straight which should set the scene for a spectacular sprint finish.

"He (Dumoulin) has been cleared to race by the team's medical staff, but is still suffering with his knee," his Sunweb team said.

"He will give it his best shot and see what the day brings."

Dumoulin came second at both the Giro d'Italia and the Tour de France in 2018, as well as winning the 2017 Giro and the 2017 world championships time-trial, making him a chief contender in all major tours and races.

"For sure, the overall ranking is over for me," Dumoulin said on Tuesday.

The 28-year-old was in 56th position 4min 30sec behind race leader Primoz Roglic of Slovenia.

"There is no fracture, which is good news, but my knee is very swollen," he added.
