Dundee United forward Collin Samuel's proposed move to Toronto is in doubt after the 25-year-old's entry into Canada was blocked by immigration officials.
The Trinidad & Tobago international, who has been released by the Tangerines, was told he should have applied for a full working visa.
Samuel's agent, Raymond Sparkes, said: "Toronto are getting crowds of 20,000-plus and want to have Collin on board.
"We just didn't have enough time to apply for a visa so the result was he couldn't fly out.
"I know Toronto are disappointed, but I still believe (coach) Mo Johnston is keen to follow through with his interest.
"Collin will go back to Trinidad as soon as the season finishes and then we'll see what happens after that."
