Tom Elliott is due to have a medical at Millwall on Friday before completing his free transfer from AFC Wimbledon.
Elliott has agreed terms and will become the second summer signing at Millwall, who were promoted to the Championship via the play-offs, following the arrival of James Meredith from Bradford.
The 26-year-old forward, who scored 13 goals for Wimbledon last season and was named their Player of the Year after an impressive campaign in League One, is out of contract and rejected a new deal to stay at the Dons.
Elliott is set to compete for regular game time with Lee Gregory and Steve Morison, who scored the winner in Millwall's victory at Wembley earlier this month.
Meanwhile, Elliott's impending departure is set to leave a sizeable hole in Neal Ardley's front line as the Dons are often deployed in a three-pronged attack with Elliott playing a central role.
But the south Londoners, who finished 15th in their debut season in England's third tier, have brought in Kwesi Appiah on a free transfer in order to bolster their attacking options.
