Defender Gavin Gunning claims he failed a medical at Sheffield Wednesday before joining Birmingham City this summer.
The 23-year-old was strongly linked with a move to Hillsborough following the conclusion of the 2013/14 campaign.
After opting to run down his Dundee United contract, Gunning says he was on the brink of a permanent switch to Wednesday but claims they ended their interest in him after he failed a medical.
He ultimately penned a one-year contract with their Championship rivals, with a 12-month option, and officially became a Blues player last week.
“The medical situation was well publicised,” said Gunning. “I went to Sheffield Wednesday and had a medical.
“Then I came here to Birmingham and passed the medical. So I don’t know how I could fail a medical and at the same time pass a medical here at Birmingham.
“I’m now here at Birmingham and hopefully I will do well. I’ve moved to England to further my career. I will be making a step up and then see where it might take me.”
Gunning played 33 times for the Tangerines last term as they finished fourth in the Scottish Premiership and reached the Scottish Cup final.
When asked about Gunning in May, Owls boss Stuart Gray said: “There are going to be names that are thrown about. I would imagine it is the agents trying to create a bit more interest.”
Meanwhile, former Owls forward Nejc Pecnik has hinted he would be interested in returning to British football.
The 28-year-old, who played 14 times for Wednesday during the 2012/13 season, currently plays for Red Star Belgrade but has been linked with a move to Celtic.
Pecnik said: “I have not had any contact with Celtic.
“But I would be happy to return to Britain, even at Championship level.
“When I was at Sheffield, the manager gave up on me too soon. I’m sure that I could play a prominent role in this league.”
