Tony McCoy is leaning towards riding Don't Push It in the John Smith's Grand National.
The 14-times champion had been considered likely to partner Can't Buy Time in next Saturday's Aintree feature, but current ground conditions have forced a rethink.
Don't Push It and Can't Buy Time are both trained by Jonjo O'Neill and owned by JP McManus.
"There's no pressure to make a final decision until nearer the time, but having originally been pencilled in for Can't Buy Time, I now find myself leaning towards Don't Push It," McCoy told the Daily Telegraph.
"You can forgive Can't Buy Time his run in the race last year - he eventually fell at the 18th - because he went there on the back of a hard race in the four-mile chase at Cheltenham, but there is a slight question mark about his stamina and he definitely wouldn't want the ground too soft.
"To my mind, Don't Push It has a bit of class and ability, and he'd be fine on that ground.
"That is my thinking at the moment, and I reserve the right to change my mind several more times!"
