Katie Walsh has passed the course doctor so she can ride Wonderful Charm in the Randox Health Grand National at Aintree.

Walsh, third in the 2012 National on Seabass, was unseated from Distime in the Foxhunters' Chase on Thursday but has now proved her fitness in time for the big race.

She said: "I'm fit and ready to go and really looking forward to it."

Wonderful Charm was pulled up before the 21st fence in last year's Grand National.
