Madrid - Dani Pedrosa had successful surgery on a persistent arm problem on Friday and is expected to be sidelined for four to six weeks, the Spaniard's Repsol Honda team said.
Pedrosa, 29, will miss the MotoGP in the United States on April 12 and the race in Argentina a week later while he recovers from the operation.
Repsol Honda added that test rider Hiroshi Aoyama will temporarily take Pedrosa's place in the team alongside world champion Marc Marquez.
