FRANCO di Santo should find out in the next 24 hours the full extent of his mystery ankle injury.
The Argentinian striker has been to see a specialist in London to get the bottom of a problem that has dogged him for the best part of two months.
Di Santo suffered the injury in the 2-2 draw at Newcastle in mid-October, after creating both Wigan goals for Charles N’Zogbia.
Since then, he has been playing through the pain barrier, but Latics have decided that enough is enough – and manager Roberto Martinez is now sweating on the verdict.
He told the Evening Post: “We sent Franco to see the specialist and are now waiting for the full diagnosis.
“He picked up the problem at Newcastle and has been struggling with it ever since.
“We’ve been managing it carefully to make sure he has remained available, but the West Ham game last week was the final straw.
“It was just impossible for him to continue, impossible for him to even kick a ball.
“We need to get to the root of the problem as quickly as possible and correct it.”
Di Santo’s form had understandably dipped in the past few weeks after a fine start to his Wigan career following his summer arrival from Chelsea.
And Martinez is adamant the best interests of both the player and the club will be served by identifying and rectifying the problem.
The Wigan manager added: “He’s already had a couple of scans and an MRI, but at the moment nothing’s proved conclusive.
“It’s in a very deep part of his ankle, quite high up, which is making it difficult to tell what’s wrong.
“There’s nothing we can do until we get the specialists report back, because it could be two or three different things.
“We’ll find out for certain in the next day or so, and then at least we’ll be able to treat it. But I’m quite positive and remaining optimistic about the whole thing.
“The ankle settled down a lot over the weekend, and I’m sure if it had have been a major problem then it wouldn’t have done that.”
