McKay only joined the Reds last summer from Rangers but despite featuring heavily in the first half of the campaign under Mark Warburton was a peripheral figure under new boss Aitor Karanka during the second half of the season.
It now looks as though McKay’s stay at the City Ground will be short-lived with WalesOnline reporting a deal is close to being agreed between all parties ahead of the new Championship season getting under way this weekend.
Forest have brought in a plethora of attacking options this summer as Karanka plots a route back to the Premier League - and the Reds boss is still hopeful of adding a right-back to his squad, which would be an 11th signing this transfer window.
