Henry de Bromhead said it was "50-50" which race Sizing Europe will run in at Cheltenham after he was officially scratched from the Betfred Gold Cup.
The Waterford trainer had indicated he might do that after his latest success in the Tied Cottage Chase over two miles at Punchestown earlier this month.
The sportingbet.com Queen Mother Champion Chase and the Ryanair Chase remain the two options for the talented 11-year-old.
Sizing Europe is already a dual winner at the Festival, lifting the Arkle Trophy in 2010 and the Champion Chase in 2011 as well as finishing second in the latter event last year.
He has been successful at around two and a half miles, with two of his four victories coming at this trip this season.
"He's out of the Gold Cup and we've put him in the other two for the moment," said De Bromhead.
"We've no idea which race. It's definitely 50-50 now.
"We are always looking forward to Cheltenham when he's running. He's been super.
"He seems in good form, he seems well and we're happy with him at the moment."
