Unless he moves from Wigan, who looks as if they are going to be in Div 1 next season, I think it is unlikely.
If it wasn't for Powell, they'd be pretty much down already, it's only his four goals in the last two games that's given them any chance at all (though it's almost certainly come to late to save them).
True, always felt there was a player in there somewhere, but he hasn't pulled up any trees at Wigan apart from as you say his goals in the last few games.
Plus the manager has recently said he can't start games "cos it might jeopardise his career". Sounds like his injury troubles are far from over.
