Vincenzo Nibali and his Astana team have apologised after the Italian was disqualified from the Vuelta a Espana for being towed by a support car.

Nibali was pictured being helped up the road for five seconds as he tried to regain ground after a crash on Sunday.

"I thought I'd get a fine and time penalty that would take me out of the overall classification. After all, I won't be the first or last to do this kind of thing."

Colombia's Esteban Chaves leads the general classification at the Vuelta by five seconds after two stages of a race that ends on 13 September in Madrid.

Britain's Tour de France champion Chris Froome is chasing a Vuelta-Tour double that has been done just twice before.
