Alan Gow has this morning has failed a medical at Wolves.
the news ends Wolves interest in Gow this transfer window.
"We'd agreed everything with him and it was fine but something has shown up in the medical which we are not completely happy about and he's gone back up there to get it checked out.
"It's not serious, something bio-mechanical, but that's something for Alan and Rangers rather than us." McCarthy told the clubs official site.
With McCarthy still looking to strengthen this January, Steve Morgan may now find he has to dig significantly deeper into his pockets to secure any of Wolves other targets, possibly having to break the 7 figure barrier.
