Pramac Ducati's Hector Barbera looks certain to miss next weekend's US MotoGP at Laguna Seca.
According to the team, Barbera “suffered injuries, during a training mishap near his home, in Spain” adding that the injuries included a broken “left fibula and shinbone”.
Barbera will undergo surgery on Sunday, at the Insitituto Universitario Dexeus in Barcelona, to be performed by Dr. Xavier Mir.
An estimated recovery time is to be issued after surgery and the Pramac Team will then “decide the plans for the foreseeable future”.
Barbera, who claimed his first ever MotoGP front-row start at last weekend's Mugello round, is eleventh in the championship with a best race finish of seventh.
Fellow satellite Ducati rider Karel Abraham is expected to make his return from injury at Laguna Seca.
