Connections of Junior will monitor the horse's condition ahead of the Coral Scottish Grand National at Ayr on Saturday.
The David Pipe-trained nine-year-old has a slightly swollen joint following his fall at the second fence in the John Smith's Grand National at Aintree last weekend.
Another concern is the likely soft ground north of the border as Junior would have to carry top weight of 11st 12lb in the stamina test over an extended four miles.
"He's fine, he's happy. He did rap a joint which is a tiny bit swollen and we have to monitor that during the week as to whether he runs in the Scottish National," said Tim Palin, racing manager to owners Middleham Park Racing.
"It also depends on what the ground is. He's got top weight and it's possible he might wait a week for the Bet365 Gold Cup at Sandown. We'll have to see if his joint settles down."
Palin was delighted Junior returned safe and sound after being caught immediately after his fall by jockey Tom Scudamore.
"Tom caught him straightaway and they walked back together," he went on.
"We were worried because we didn't see the horse run back but it was because Tom had caught him, so it took them a while to get back."
Irish trainer Maurice Phelan has no such worries about Portrait King, who returns to these shores attempting to supplement his triumph in the Eider Chase at Newcastle in February.
"He's had a good break since the Eider and he's ready to go again," Phelan told At The Races.
"He won't give up and he toughs it out. He showed in the Eider that he stays and stays.
"He was always going to be a four-mile horse and jumping is his game. He should be thereabouts with luck in running over those 27 fences.
"It looks like being soft, which should be perfect ground for him."
