Carruthers will miss the Betway West Wales National at Ffos Las on Saturday after an 11th hour setback.
Mark Bradstock's 12-year-old, who won the race two years ago, had been an intended runner but trod on a stone and will not recover in time.
"It's unfortunate, but as the ground is likely to be sticky, rather than sloppy, we're not as upset as we could have been," said Bradstock's wife, Sara.
"He just trod on a stone and he's the sort of horse that feels pain more than some others, he's a bit precious. He'll probably be fine by Sunday.
"We'll look at running him in some veterans' races now, I'm sure there's a couple of races in him.
"He's showing all his old enthusiasm at home, it's just that as he's got older he's found it harder to cope with sticky ground.
"I'm sure he's well handicapped, he's a stone lower than when he won the Ffos Las race a couple of years ago."
