The Farnworth-born custodian has refused to confirm his latest deal will be his last, although he does admit he is already planning for life after playing.
"I'm no spring chicken anymore, I'm 40 now, and those things are at the back of mind increasingly," he told Wigan Evening Post.
"When I first joined Wigan, at 33, I thought I'd give it two years and then see what happens - and seven or eight years on I'm still here.
"Ideally I want to stay in the game when I do call it quits, but all I'm thinking about at the moment is keeping on playing for now.
"I've done my Level 3 coaching now, next up is the A-Licence, and I am enjoying it.
"It's a lot different from being a player - instead of just turning up for training, a coach has to plan the session, keep it fresh and so on.
"There's obviously a lot more responsibility being a coach, but it's something I'm looking forward to pursuing one day."
