“I want to see how he comes through this race on Saturday first before I look at his next start,” Duncan said.
“He’s been in work for around three months and so far, the leg is fine and he’s working strongly but he might just need this run.”
Magnufighter showed he was ready for his comeback finishing fourth in a barrier trial at the Sunshine Coast last month and is a proven performer first up with two wins and a second from eight starts.
His biggest career win was in the Gold Coast Stakes over 1800 metres in March last year.
Duncan has long believed Magnufighter is capable of winning a big race even though he’s approaching the twilight of his career.
In his youngster days, Magnufighter finished second as a three-year-old in the Group 2 Queensland Guineas in 2018.
He also finished second in the Listed Member’s Cup at Doomben in February last year.
Duncan rates the Lismore-trained At Witz End as the hardest to beat following the gelding’s recent run of three wins from his past four starts.
Duncan had been training for more than 30 years and moved from Atherton in the state's far north to Caloundra on Queensland's Sunshine Coast about a decade ago.
