Trinidad and Tobago striker Jason Scotland will have to wait for a visa and international clearance before his move to Wigan can officially be completed.
The 30-year-old was granted a work permit at an appeal hearing on Wednesday but further paperwork must be received before his transfer from Swansea can be sealed. He has already passed a medical and agreed terms on a two-year contract but could still miss the Latics' pre-season trip to Austria next week if the necessary documents do not come through in time.
A fee, believed to be around £2million, was agreed between the two clubs on Friday and Wigan boss Roberto Martinez said: "Jason is a natural goalscorer, I can't really put it any other way. Every manager wants a player who has that clinical ability to make something happen in the box, and Jason can do that."
He added: "He is strong, very physical, and his feet can produce the magic ingredient every team needs in the box.
"This was always going to be a key signing for me.
"I have every faith he can make the step up to the Premier League and become a real cult hero at the Latics.
"I know from experience how the Wigan fans love a goalscorer. Graeme Jones, Andy Liddell, Nathan Ellington, Jason Roberts. I am confident Jason can be the next name on that list."
Scotland is delighted the move has finally been sealed.
"I am so excited to get a chance in the Premier League," he said. "I want to show the manager he has done the right thing by bringing me here.
"I loved my time at Swansea and I think I served the club well but a new chapter in my career starts now."
