Tiger Roll is only ‘50-50’ to run in the Grand National at Aintree in April, where he would bid to emulate the great Red Rum with three victories over the famous fences.

Connections of the Gordon Elliott-trained ten-year-old are disappointed at the way the weights have been framed for the race, in which he would carry top-weight of 11st 10lb, the same weight allotted to stablemate Delta Work, the winner of the Irish Gold Cup.

Tiger Roll had a setback earlier in the season and is due to return in the Boyne Hurdle at Navan this weekend.

Eddie O’Leary, racing manager for his brother Michael’s Gigginstown House Stud, told Sky Sports Racing: "Hopefully he comes through the Navan test, he's coming back after a setback - he won't win, obviously, but if just pulls up with a smile on his face that will do us and then go on to Cheltenham and hopefully show us more there.

"Then we'll decide, but at the moment it's 50-50."
