Sam Thomas will be reunited with Denman in the Hennessy Gold Cup on Saturday week.
Thomas did the steering when the 10-year-old won the prestigious handicap in 2007, but has not partnered the popular chaser since the partnership came to grief at Aintree last April.
The 2008 Gold Cup winner will be bidding for a historic third victory in the Hennessy, in which he must shoulder top weight of 11st 12lb.
Denman is likely to be one of five Nicholls representatives in the Berkshire showdown.
"Sam Thomas will ride Denman," the Ditcheat handler confirmed in his column on www.betfair.com.
"Nick Scholfield will partner Taranis, Noel Fehily is on board Neptune Collonges, and Ryan Mahon gets on The Tother One.
"And if Harry Skelton is back in time from injury, he will ride Niche Market - if not, Ian Popham will."
Fehily, meanwhile, is due to get the leg-up on Big Buck's in Newbury's Long Distance Hurdle on the same afternoon.
