John McPhee has been ruled out of this weekend's Indonesian Moto3 Grand Prix after fracturing tw𒅌o vertebrae during a Supermoto training acc🦩ident.

Fortunately for the Scotsman, who finished fifth on his debut for the 💞Sterilgarda Husqvarna Max racing team in Qatar, the fractures ar♉e 'stable and there is no need for surgery'.

McPhee is now starting rehabilitation ꦫ'with the intention of returning for the Argentine Grand Prix, which will be held on April 3'.

A statement from Max Biaggi's team confirming the injuries also noted that McPhee, who made his grand prix debut back 🉐in 2010 on a 125cc two-stroke, has neve🐬r missed a grand prix due to a training injury before.

Assuming no last-minute replacement is found𓆉, Ayumu Sasaki, who led for much of the Qatar race befo༒re suffering a near highside and fairing damage, will be the only Max Racing rider at Mandalika this weekend.

Unlike MotoGP, the Moto2 and Moto3 classes♑ did not have a pre-season test at the new Mandalika c🍎ircuit, which has also undergone 25% resurfacing ahead of this weekend.
