Chaz Davies has sustained a fractured right collarbone in a training accident at Aragon and faces a race against time to be fit for the return of the World Superbike championship at Portimao.

The Racing Ducati rider suffered a near-identical injury at the start of World Superbike’s lengthy summer break which saw him miss the Italian manufacturer’s ‘Race of Champions’ at Misano. The Welsh rider had made a sufficient recovery to take part in last week’s in-season test in Portugal but has suffered a fresh setback while training at Aragon.

Davies has been hit with a right collarbone fracture and spent the night in hospital under observation for medical tests to determine whether he will need further surgery. The Ducati rider underwent surgery just over a month ago on the same area.

Both Davies and his Ducati squad are hopeful he’ll make a full recovery in time for the next World Superbike round at Portimao which is now two weeks away (September 14-16). No provisional replacement rider has been announced.

Ducati recently xonfirmed the re-signing of Davies alongside Alvaro Bautista for the 2019 World Superbike championship, who will switch from MotoGP over the winter, to take up Marco Melandri’s ride.

Davies is currently second in the World Superbike riders’ standings but a significant 92 points behind championship leader Jonathan Rea with four rounds – and a maximum of 200 points – remaining.
