Reigning MotoGP World Champion Marc Marquez had to undergo a second surgery on his injured arm after opening a window broke the metal plate holding it together.

It would appear that after putting the plate through plenty of stress at Jerez last weekend, the act of opening a window was the last straw for the titanium.

“As you know last Monday Marc had another surgery on the humerus due to the crash at Jerez in the grand prix,” said team boss Alberto Puig.

“It was a domestic accident this time because he was trying to open a window and he suddenly felt a lot of pain and later we could see that the plate was broken.

“This is caused after all the stress that he had in the arm, but as you know we went to Jerez with conviction that we could do it.

“The doctors were OK to do it and they never informed us that the plate could have broken.

If we had this info, probably he wouldn’t have gone to Jerez, Honda will not have given him the chance to ride.

“But the positive point is that this happened in his house, not at Brno on the bike, or in Austria, which could have had massive consequences in case he had another crash.

“From now on we will have to continue to check the development of his fracture and only time will tell when he’s ready to go back racing.”

It is the strangest reason for not taking part in a race after Valentino Rossi 'fell through a table' when closing some curtains in 2009.
