The Scottish left back is due to arrive at West Ham’s training ground today and is set for a medical after which the formalities will be concluded.
Speaking to the Daily Record, his representative said: Stephen is delighted everything is now in place and his future is settled.
“He will play out the rest of the season at Hamilton ahead of a terrific move in the summer. Not even the snow was going to stop the deal.”
Hamilton were furious with West Ham over the month-long transfer saga, when the Hammers pulled out of a deal at the last minute, only to now sign the defender at a bargain price in the summer.
Sam Allardyce confirmed the deal saying: “It’s with view to a move in the summer yes. He’s one for the future, not for now.”
