War Of Attrition is set to sign off his career at next month's Punchestown Festival after showing up well for a long way in last week's World Hurdle at Cheltenham.
The 11-year-old was making his first visit to Prestbury Park since landing the 2006 Gold Cup but after making much of the running he faded to finish 12th.
Trainer Mouse Morris admits his veteran is not the force of old but wants his pride and joy to bow out on home soil.
"He gave a good account of himself and all being well he'll now go to Punchestown as we've taken him out of the National," said Morris. "I've left him in the Guinness Gold Cup and the three-mile hurdle race and we'll just see how the ground is nearer the time before we decide where to run.
"Whatever happens it will be his last race and it would be nice for him to go out in the chase, but we'll see.
Twice Over's Dubai World Cup hopes have been dealt a blow after Henry Cecil's charge drew stall 11 of 14 for the world's richest race. Last year's Champion Stakes hero has been off the track since finishing third behind Zenyatta in the Breeders' Cup Classic last November but had been in top spot in the World Cup ante-post lists.
Coral clearly feel his wide berth is a hindrance to his challenge and have pushed him out to 11-2 from 5-1 and promoted French raider Vision D'Etat (stall six) to 4-1 favourite from 9-2.
The draw was seemingly kinder to Marco Botti's recent Lingfield winner Gitano Hernando, who will break from stall two in the hands of Kieren Fallon.
Christophe Clement's Gio Ponti was a place ahead of Twice Over in the Breeders' Cup Classic and connections appear happy to have drawn stall four.
