New Zealand's Hayden Roulston was forced to pull out of the Tour of Spain overnight, after feeling dizzy following a head knock in a crash on Thursday's stage.
Roulston withdrew after discussions with RadioShack Nissan team.
This morning (NZ time) Roulston went to a hospital for a scan. Although he was unable to do an interview, Roulston sent a text to Fairfax Media saying "Yesterday I crashed hard and hit my head.
"I never started the day as I felt off, dizzy and just unwell."
It is desperately unlucky that Roulston has had to pull out as he had targeted the third week of the Tour of Spain as the time when he would look to get into an early break and go for the stage win.
The only New Zealander left in the final grand tour of the year is Julian Dean.
The Orica GreenEDGE rider finished the 172km stage 13 from Santiago de Compostela to Ferrol 10 minutes behind the eventual winner Stephen Cummings from Great Britain.
Spain's Joacquim Rodriguez still holds the overall lead in the race with a 13-second lead over Alberto Contador.
