Marc Marquez to miss Czech MotoGP after second operation on his arm

Reigning MotoGP world champion Marc Marquez will miss his second straight race after he was ruled out of Sunday's Czech Grand Prix following another operation on his fractured right arm, his team said Tuesday.

"After undergoing a second operation on his injured right arm, Marc Marquez and HRC have decided that the world champion will not ride in the Czech Republic in order for him to recover more," Repsol Honda said in a statement.

The Spaniard underwent further surgery Monday in Barcelona on the arm he broke in the season opener in Spain on July 19. He missed the following race in Jerez despite initially being declared fit to take part, just 48 hours after having a titanium plate inserted.
