Murphy has warned Brewin’upastorm is far from certain to make his first start after a setback in the Grade Two Kingmaker Novices’ Chase at Warwick on February 8.
The seven-year-old, who is as short as 10-1 for the Arkle at the Cheltenham Festival, has not been sighted since making it two from two over fences at Taunton in November.
Murphy said: “It will be touch and go if I have him ready for Warwick. I won’t be going there if he is 75 per cent.
“If I don’t get him there, he will have a run round in a novice at a little country track, just to get a bit more experience.”
