2008 Grand National Runner-up King Johns Castle has been ruled out of the 2009 race due to a tendon injury.

Trainer Arthur Moore reported today that the gelding would be out for the season but that hopefully he would come back into training for the following year.

Has this upset many early ante-post bets for Grand National Guide readers? Will Tony McCoy be cursing as he may well have switched to this horse in his search for that illusive Grand National winner?

Can King Johns Castle come back to challenge for Aintree honours again after an injury like this?

Let us know what you think?
