Stuart Crawford feels Fine Rightly is back to himself ahead of his tilt at the Coral Scottish Grand National at Ayr on Saturday.
Last season's Irish Gold Cup third has been below par for his last two races, running down the field in the Lexus Chase before his fourth of five finishers at Kelso.
"Hopefully he's coming back into form again now," said the County Antrim handler.
"Ideally, we'd like softer ground, but as long as it's safe he'll take his chance.
"There was a bit of a virus, or something, hanging over him for his last two runs and I think that was down to those two disappointing efforts.
"The last day at Kelso it looked like he was going to be the winner and by how far, but he didn't get home and that was probably the lowest-rated race he's run in in the last two years, so there had to be something amiss with him."
Pat Griffin was delighted with Portrait King's performance in the Topham at Aintree where he was third to Ultragold over the Grand National fences.
"He ran very well at Aintree and we just hope he can run the same race again," said the County Dublin-based trainer.
"The extra distance will be up his street and he should benefit from the ground as well."
Griffin also saddles Man With Van, who was the last horse to make the cut in the maximum 30-runner field.
