Glasgow Rangers striker Alan Gow’s transfer to Wolves is off after he failed his medical.

Wolves boss Mick McCarthy revealed a “biomechanical” problem had prevented the transfer from Rangers going through.

But he stressed it was “not serious” and hasn’t ruled out signing the 26-year-old in the summer, when the problem is sorted out. Biomechanical relates to the skeleton.

Following stringent tests from the Wolves medical team, the club have put the deal on ice.

McCarthy said: “He can continue to play Saturday, Tuesday, Saturday, Tuesday – it’s a biomechanical thing that he will get sorted.”

A fee of £250,000 had been agreed between the clubs and the 26-year-old had also sealed a two and a half year contract, pending the medical. McCarthy reckons the exact nature of the problem would have to be revealed by the player or Rangers.

He said: “He’s gone back to Rangers. He’s had an extensive medical but something’s been found that we’re not completely happy with. He’s gone back to have it checked out.

“It’s not really serious and it’s something that can be sorted out, but we’re not going ahead with the deal on the strength of it. It’s really the fact that our medical team were really thorough.

“We had agreed everything and we were really looking forward to having him, but we’re not going to take him at the moment. Not in this window.”

McCarthy believes the minor nature of the problem meant Gow could carry on playing, as he had just reeled off 17 appearances for Blackpool on loan.

The Wolves boss said: “He could carry on playing tomorrow.”

McCarthy hasn’t ruled out signing Gow in the future, after failing with a bid for him in the summer of 2007 when he signed for Rangers.

The Molineux chief added: “He’s a good player – I tried to sign him before. He would have been a really good signing, who would have covered us in a number of positions.”
