Home star Nicky Hayden has been declared unfit to race in Sunday's Indianapolis Mo🐽toGP.

The Ducati rider highsided heading into turn 14 with eight minutes of Saturday's qualifying hour remaining ꦯand was briefl🌃y knocked unconscious, prompting the deployment of red flags for the second time, after Casey Stoner's earlier fall.

See below for a full picture sequence.

"After an initial check at the track's Medical Center, the American was transferred to Indianap༒olis' Methodist Hospital, where additional examinations revealed two small🦋, non-displaced fractures to the second and third metacarpal on his right hand," said a Ducati statement.

"The results of the CAT were negative, and the American should be discharged this evening or tomorrow morning, but in any case ♑he won't take part in the Grand Prix."

Hayden, who took his first Ducati podium at Indy in 2009, had qualified as the top Desmosedici rider in e💞ighth place.

Reigning world champion Stoner suffered ankle ligament damage in his highside and is yet to ꦇbe confirmed for the grand prix.

Ben Spies - who also suffered a heavy fall at the same turn - injured his shoulder but ꦏhopes to ride.
