Zurlo pushed Voss into the kerb at the first intermediate sprint at Yas Marina Circuit, 91.3km into the race, after which the latter apparently lost his temper and reacted physically, with Bora-Argon 18 director Ralph Denk admitting there had been a “scuffle” between the two riders, although it remains unclear exactly what went on.

The official jury communiqué says Voss was disqualified due to “an act of violence amongst riders”, while Zurlo emerged unscathed despite his aggressive manoeuvre.

Voss, who was holder of the black jersey after stage one, apologised for his behaviour.

“For the second time in a row I was the rider who initiated the group of the day. I wanted to defend the sprint jersey, which I am very proud of, and I was very motivated to race,” said Voss in a statement.

“At the first intermediate sprint, I was in a good position. Zurlo launched the sprint for his teammate, then he crossed intentionally my sprint line. I had to give way and brake hard in order not to ride in the kerb and crash. Of course, I was upset. I am very sorry that the adrenaline was a little high with me afterwards and I apologise to Federico Zurlo for my behaviour.”

Denk said the two riders had already settled the issue during the race and was surprised to see Voss disqualified.

Denk said: “Sprints are always competitive. Unfortunately, a short scuffle occurred afterwards. Of course, this shouldn’t happen. I just talked with two guys again and for them the issue was settled in the race already. Therefore both were surprised that the jury took this decision. But we have to accept it.”

The stage was won by Team Sky’s Italian sprint specialist Elia Viviani, who perfectly-timed his attack to squeeze past world champion Peter Sagan and EttixQuick-Step’s Fabio Sabatini.

Sagan said: “I was there but it’s the last race of the season, so easy and relax. Elia Viviani was my team-mate (at Cannondale) so I’m happy for him.”

Asked if he has his eyes on Sunday’s final stage featuring another bunch sprint finish, Sagan said he shouldn’t be discarded from Saturday’s mountain stage in Al Ain.

“Why Sunday? I’m good in the mountains. We’ll see,” he added with a smile.
