Rangers have opted not to follow up their interest in Nigerian striker Michael Uchebo, who trained with the club on Thursday.
The 20-year-old is out of contract in the summer and Dutch club VVV Venlo are seeking a fee in the region of £1m.
"He came in and trained but he's left again - that was a club decision," boss Ally McCoist told his club website.
"We thought it was in the best interests of us and him that he pursued other options."
And McCoist added: "To my knowledge there has been absolutely no contact between the clubs, never mind a fee agreed."
The Nigeria Under-20 international has scored one goal in 13 appearances this season in Holland's Eredivisie.
Uchebo also had a spell on trial at Stoke City this month, but manager Tony Pullis decided against a move for the towering target man.
McCoist revealed that Honduran Jorge Claros remains on trial at Murray Park, where Luigi Bruins has also been training this week.
Estonian full-back Enar Jaager and striker Zlatan Muslimovic have moved on after brief periods in Glasgow, though the Rangers manager was impressed by the former and did not rule out a future move.
"We were not in a position to make him an offer but I'm certainly not going to close the door on that," he said of Jaager.
"If the opportunity arises and we're in a position to make a bid then we'll do that."
Another duo who have been linked to the Ibrox club are Rapid Vienna's Albanian forward Hamdi Salihi and Polish striker Pawel Brozek of Trabzonspor.
McCoist said: "Salihi is a player we've very well aware of. There's no movement at all but he's a player we're aware of.
"Brozek is the same. These are players that we're aware of and in an ideal world we might be able to get them to the club but there's nothing for me to tell you at the moment."
