Sir Bradley Wiggins suffering from chest infection at Giro d'Italia

Team Sky's Sir Bradley Wiggins said he was suffering from a chest infection after finishing in the pack on stage 11 of the Giro d'Italia.

The 2012 Tour de France winner came home alongside his main rivals to retain fourth place in the standings.

"I'm not feeling very good at the moment, I've had a pretty rough 24 hours," said Wiggins, 33.

Lithuania's Ramunas Navardauskas won the 182km stage while Italy's Vincenzo Nibali kept the overall lead.

Wiggins, who crashed on the seventh stage, is two minutes and five seconds behind Nibali as he bids for his first Giro d'Italia victory.

"I've got a chest infection and a bog-standard head cold," he said.

"Fortunately in these days, these kinds of stages, there's just a bit of fighting and you can get through them and hide a little bit.

"But I just want to try and fight through it and hope that in a few days' time I'll be all right.

"Most of the team have been sick. It seems to last for three or four days and then you get better."

After a torturous stage on Tuesday, Wednesday's smoother route, from Tarvisio to Vajont, provided light relief for the riders with the field content to stay together for much of the opening downhill section.

But as they approached the category two climb up to Sella Campigotto, a breakaway of 20 riders, including Garmin Sharp's Navardauskas, launched an attack.

The peloton, which contained Nibali, Cadel Evans, Rigoberto Uran and Wiggins - the top four in the general classification - were content to allow the escapees to build a gap as none posed a serious threat to their overall position and Navardauskas won in a time of four hours and 23 minutes.

"My team decided to let the break go and then keep things under control behind," said Nibali. "But there will be harder days to come."

Argos Shimano rider Patrick Gretsch, who finished inside the top 15 in the stage eight individual time trial, broke away from the peloton with 50km to go and built up a lead of two minutes.

However, the German ran out of energy at the foot of the final 7km ascent to the finish, allowing Navardauskas and Daniels Oss to race clear.

Navardauskas, who had been allowed to attack in this stage following team-mate and defending champion Ryder Hesjedal falling out of contention after stage 10, found another gear.

The Lithuanian pulled away into a clear lead and held on to win the second Giro stage of his career, one minute and eight seconds clear of Oss.

"We've not been so lucky in this race," Navardauskas said. "Ryder has had some bad days, and has not been so fortunate, so as a team we wanted to try and turn things around today. All of us wanted to get in a move.

"It was a long day off the front, but I got in the right break and managed to turn it round for the team. I couldn't be happier."

Stefano Pirazzi, who holds the King of the Mountains blue jersey, was third.

Wiggins, Nibali, Evans and Uran rolled across the line five minutes and 41 seconds adrift, their positions in the general classification unchanged.

Earlier in the day, it was announced that French rider Sylvain Georges has failed a drugs test at the Giro d'Italia. He withdrew before Wednesday's stage.

Thursday's stage is a 134km route from Longarone to Treviso. It should suit sprinters like Mark Cavendish, providing he can negotiate the two short, sharp climbs in the middle third of the race.
