Sam Gallagher is having a medical with Blackburn ahead of a move from Southampton, Sky Sports News understands.
Sky Sports revealed last week that Blackburn were expected to make a formal bid for the striker, but he is now undergoing a medical after a fee was agreed between the two clubs.
Tony Mowbray's side had been in talks with the Saints for two weeks - but despite interest from Wigan and Brentford the 23-year-old looks set to move to the North West.
Gallagher spent the 2016-17 season on loan at Ewood Park, scoring 11 goals, and was loaned to Birmingham the following campaign, top-scoring for the Blues in the league with six goals.
Southampton, who did not take him on their pre-season trip to Austria, want a deal of around £5m for the former England U20 striker, who spent last season on loan at Birmingham City.
