The Ospreys have been boosted by the surprise return of Nikki Walker and Jamie Nutbrown to their squad for the EDF Energy Cup tie with Worcester this Sunday.
Scotland wing Walker suffered a broken hand in the Heineken Cup loss at Leicester two weeks ago while Nutbrown also returns following a foot injury.
Gavin Henson is expected to start after his disciplinary problems and after only playing one match this season, will be desperate to get some game time ahead of the Invesco Perpetual Autum Series, having only played one full match this season.
Duncan Jones said: "We had a tough game against Harlequins and the win was all important. We do not want to let go off this trophy easily as champions.
"We recorded a good win away to Worcester last season but we will not be complacent. They are a totally different side, we understand it will be physical but we're up for the challenge and looking for a win."
