A former point-to-pointer, Samuel Jackson has won both his races under Rules to date, the first at 100-1 at Taunton.
He proved that was no fluke by following up from a decent rival at Bangor earlier this month and fully warrants a crack at Grade Two company.
Mitford-Slade, whose record currently stands at three winners from just 10 runners, said: "He is very well. I was a bit worried this race at Doncaster would come too soon, but he has come back bucking and squealing so it will be interesting to see how he goes up there.
"To be perfectly honest, I thought we would end up handicapping with him, but he has clearly shown he is better than that so we will put him in equal company up there and see how he goes.
"The Albert Bartlett (at Cheltenham) is still a possibility."
