Cycling: Bora-Hansgrohe riders crash into waltzing spectator at Tirreno-Adriatico

An oblivious spectator caused a high-speed crash, after walking out in from of cyclists during the Tirreno-Adriatico race in Italy.

During the 21.5km team time trial, Italy's Oscar Gatto and Poland's Rafal Majka collided with the man, who was casually walking across the road with his head down.

Security tried to warn the man, but were too late to avoid a bone-thudding crash.

The Bora-Hansgrohe squad, which included Slovakian star Peter Sagan, were in the first 3km of their opening stage, when the crash happened.

Both Gatto and Majka finished the stage, although they'll need to be assessed before stage two. The pedestrian was taken to the hospital, but his condition was reportedly not serious.

"Initial reports indicate that Oscar Gatto has sustained some bruising, while Rafal Majka went down somewhat harder," the team tweeted.

"Further testing will need to be done to evaluate their injuries. However, both riders finished the stage today."

Bora-Hansgrohe managed to finish the time trial in 20th out of 23 teams, 1m, 57s behind leaders Mitchelton-Scott.

The leaders narrowly avoided their own accident later in the day, when they almost collided with a pedestrian walking a dog.
