“Silent Explorer was a bit fat for his last run at Innisfail that’s why I’m backing him up,” Massingham said.
“Both will probably go on and run next time in the Johnstone River at Innisfail in a few weeks.”
Silent Explorer won last year's feature Johnstone River for hoop Masayuki Abe who has been booked for Friday's assignment.
While Massingham hopes to run the quinella, he rates the Georgie Holt-trained Bones as the main threat along with Rockhampton flyer Aspen Lad.
“Aspen Lad goes very fast but I think Bones will be the one to beat,” Massingham said.
Bones gave Holt one of her biggest wins of her six-year training career when he claimed the Townsville Lightning in August.
The former Victorian has won five times for Holt and is coming off a dominant last-start win over Ali’s Jab in a 950 metre Open Handicap at Cairns last month.
