The Wolves, whose last victory on their travels was against Catalans Dragons in Perpignan in May, are not yet sure of a play-off spot despite being in the top six since March and their last three fixtures are against the top three teams.
"We have consistently concentrated on our work and not lost focus wondering what might happen or not with any other team around us in the table," said coach Paul Cullen.
"We face third, second and first in the next three weeks which is more than enough for any group to concern themselves about."
Brent Grose has failed in his bid to play in every Warrington match for a second successive season.
The Australian threequarter has made 60 consecutive appearances for the Wolves, going back to September 2004, but he will miss Friday?s engage Super League trip to Leeds after failing to shake off a knee injury sustained in his side?s win over Harlequins RL a fortnight ago.
His absence will pave the way for ex-Hull FC winger Richie Barnett to make his first start for two months after being on the bench for the last six matches.
Warrington are also without club captain Paul Rauhihi through suspension while Leeds have lost veteran back rower Willie Poching, who may have played his last game for them.
The former Wakefield Trinity Wildcats skipper has announced he will retire at the end of the season and is out for up to six weeks due to a knee injury sustained in training, which looks almost certain rule him out of the play-offs.
Leeds coach Tony Smith said: ?We thought it was torn cartilage, which it was, but when he went in to repair it they found some other damage as well that has been there for a while and that made the repair more complicated.?
Poching, 33 on Wednesday, joined Leeds from Wakefield in 2002 and was a key member of their Grand-Final winning side two years ago.
Stand-off Danny McGuire, who has missed Leeds? last four games with a shin injury, has been named in Smith?s initial 20-man squad but a decision will not be made on his fitness until later in the week.
Leeds Rhinos 20-man squad: Donald, Walker, Senior, McGuire, Burrow, Bailey, Diskin, Peacock, Lauitiiti, Ellis, Sinfield, Millard, Jones-Buchanan, Feather, Scruton, Kirke, Gibson, Tansey, Thackray, Toopi.
Warrington Wolves 20-man squad: Fa?afili, Martin Gleeson, Kohe-Love, Reardon, Briers, Sullivan, Leikvoll, Swann, Wainwright, Mark Gleeson, Westwood, Wood, Barnett, Parker, Pickersgill, Bracek, Riley, Bridge, Harrison, Cooper.
