Ground rules Minella Rocco out of Grand National Top-weight Minella Rocco has been declared a non-runner in the Randox Health Grand National at Aintree on Saturday on account of the ground. Jonjo O'Neill's charge filled the runner-up spot in last year's Cheltenham Gold Cup and pulled out of this year's renewal on the morning of the race due to the prevailing testing conditions at Prestbury Park. He was a best-priced 20-1 for the world's most famous steeplechase before being withdrawn this morning. The first reserve Thunder And Roses now gets a run. The Mouse Morris trained 10-year-old unseated rider after being hampered at the ninth fence in last year's race. Thunder And Roses will be ridden by JJ Slevin. The weights for the Grand National will now be raised by one pound for all runners. The new top weight is Blaklion on 11st 10lbs.
