Pavel Sivakov has abandoned the Giro d'Italia after suffering a shoulder injury when he crashed late in a chaotic stage five.

Sivakov was selected as a joint leader by Ineos Grenadiers but the Russian rider's race ended in the first week.

The 23-year-old went down heavily after seemingly touching wheels with a team-mate in the final 15 kilometres of the 177-kilometre route from Modena to Cattolica on Wednesday.

Sivakov was able to pick himself up and finish the stage, but his general classifications were shattered by the unfortunate incident.

Ineos later confirmed Sivakov's participation in the Giro is over following a stage that was won by Caleb Ewan in a sprint finish.

The team tweeted: "Unfortunately, @PavelSivakov has been forced to withdraw from the Giro d'Italia after injuring his shoulder in a crash on today's stage. All the best for a speedy recovery Pavel!"

Mikel Landa is also out of the race after he suffered a heavy crash and was taken to hospital.

Joe Dombrowski, leader of the king of the mountains, was another rider to crash on his birthday a day after the American gave himself an early present by winning stage four.
