UPDATE: Crutchlow 'sprained ankle', but still in doubt

Cal Crutchlow has been diagnosed with a sprained left ankle following his heavy Saturday morning fall at Silverstone, but is to undergo further medical checks before continuing in his home British MotoGP.

The Yamaha Tech 3 rider, who missed last year's race when he broke his collarbone in qualifying, was initially feared to have broken his ankle in the out-lap fall.

After medical checks a message on the official MotoGP Twitter account declared: "It is confirmed that Cal Crutchlow suffered a sprained left ankle".

That seemed to clear the way for Crutchlow to return for qualifying, but a later (midday) posting announced: "Crutchlow to undergo another examination this afternoon before deciding on further participation [in] the GP."

As well as hurting his ankle, the Englishman received an all-round battering when he lowsided through the fast left-hander onto the Hangar Straight in the cold and windy conditions.

Crutchlow was already recovering from upper body injuries in a fast post-race testing fall at Catalunya.

Rookie Stefan Bradl (Honda LCR), who was also sent to the medical centre this morning, sustained a wounded left ring finger.
