Warrington coach Tony Smith is hoping to reward his thirty-somethings with new contracts.
Captain Adrian Morley, who recently turned 35, full-back Brett Hodgson, 34, hooker Micky Higham, 31, stand-off Lee Briers, 33, and back row forward David Solomona, 34, are among those out of contract at the end of the season.
Smith, who knows he must make room in the club's salary cap for their crop of emerging youngsters, said: "I love them all. They are all terrific players and terrific people and I'd like to keep them all. We'll see what we can do there."
He added: "We've started talking to them and we'll make some decisions in a little while and filter those out as we do.
"The problem is you can't keep everybody forever. We've got some good young guys coming through and you've got to create space for them eventually, otherwise there's no point in producing those kids.
"We've got to give them the opportunity to step up. I'm not saying any of those are going, hopefully they will all be staying. I'd love them all to stay, they fit into our team very well."
Morley has missed the Wolves' last six matches with a neck injury but, after being close to making his return in each of the last two games, is finally set to play against Widnes at the Magic Weekend in Manchester.
Warrington were also without second rower Trent Waterhouse, winger Joel Monaghan and Briers for yesterday's 42-12 Stobart Super League win at Wakefield which kept them in touch with leaders Wigan.
"They've been playing a lot of game time - they've a few bumps and bruises - and we're not going to take any risks on players at this stage of the year," said Smith.
"Trent will be back next week, probably Lee too and also Joel Monaghan and Mozza is telling me he's ready to go for next week so I've got a few headaches."
