MotoGP champion Marc Marquez will miss the Czech Grand Prix after having a second operation on a broken arm, with test rider Stefan Bradl replacing him for the race.

Spaniard Marquez had fresh surgery on Monday to replace a damaged titanium plate inserted after he broke his right arm in the July 19 season-opening race in Spain.

His Repsol Honda team said that the 27-year-old, who tried to return for the second race in Jerez but withdrew without qualifying, would stay in the hospital in Barcelona for 48 hours before being discharged.

Bradl has claimed three top 10 finishes at Brno from his seven starts in the MotoGP class and only once missed out on points.

The Czech race is in Brno, with Petronas Yahama’s French rider Fabio Quartararo targeting a third victory in as many races this season.
