Connections of Diamond Harry are uncertain whether the nine-year-old is over all his problems ahead of another crack at the Hennessy Gold Cup at Newbury.
Pulled up in his last three starts, connections are hoping a return to the scene of his victory in this two years ago will spark a revival in fortunes.
"He's certainly working well and he's fit to run, but with three pulled-ups obviously we are not quite sure what's going to happen," said owner Paul Duffy.
"He's well in himself and ready to run. It didn't suit him going the other way at Wincanton. As a trial, it wasn't a particularly good one. He didn't take too much out of himself there so let's hope it's brought him on a bit and he's in the right frame of mind."
Teaforthree won the four-mile National Hunt Chase at Cheltenham and was not totally disgraced on his return when down the field at Prestbury Park earlier this month.
"He has a nice weight (10st 6lb) and he loves heavy ground, so I think we'd be a bit silly not to run him," said trainer Rebecca Curtis.
"He's a horse who obviously stays well and he's come on a lot for his first run at Cheltenham. He's a big, burly horse and you can only do so much with him at home - he always takes a run or two to get fully fit."
Dessie Hughes runs Magnanimity, who arrives here on the back of a good second behind Sizing Europe in the two-and-a-half-mile Clonmel Oil Chase.
The eight-year-old has not tasted victory since January 2011 but he will taking a step back up in trip here and will have the assistance of 5lb claimer Mark Enright.
Hughes said: "He's in great form, but I don't know about the ground. He doesn't want it heavy. He'd go well in the soft, but we'll keep our fingers crossed and hope for the best."
