Loris Baz back to MotoGP as Pol Espargaro's KTM stand-in

Espargaro fractured his left collarbone in a Sunday warm-up crash at Brno earlier this month, and sat out the Czech race as well as the following weekend's Austrian GP as a result.

With test rider Mika Kallio on the sidelines due to a knee ligament injury, KTM did not replace Espargaro for either race and only fielded a single bike for Bradley Smith.

Rules mandated that KTM "make every reasonable effort to provide a qualified substitute rider" if Espargaro was unable to recover in time for Silverstone.

KTM motorsport boss Pit Beirer said at the Red Bull Ring that the team would struggle to find a replacement.

Since then, the team has signed Randy de Puniet as test rider for the rest of 2018, but de Puniet had made it clear he would only compete at Silverstone if he had a test to prepare.

KTM has instead turned to another Frenchman in 25-year-old Baz, who competed in MotoGP as recently as last year.

Baz, a World Superbike race winner, competed for Forward Yamaha and Avintia Ducati in his three seasons in the premier class of grand prix racing, before losing his Avintia ride and leaving the championship at the end of 2017.

He returned to Superbikes with the Althea BMW team this year and currently sits 12th in the riders' standings.
