Bolton are set to sign Iceland striker Jon Dadi Bodvarsson on a free transfer from Millwall.
The Trotters originally wanted to take him on loan with a view to a permanent deal in the summer.
But the frontman, 29, has negotiated an early release from his Lions contract, which was due to expire at the end of the season.
Bodvarsson mustered just seven goals in 76 appearances in all competitions for the south Londoners since joining from Reading in a £750,000 deal in July 2019.
Millwall hope getting one of the highest earners off their wage bill will allow them to make at least one attacking signing this month after in-form striker Tom Bradshaw expected to be sidelined for 12 weeks with knee ligament damage.
The Lions will also be without on-loan Liverpool winger Sheyi Ojo for 10 weeks after he suffered an ankle injury in their 1-0 home defeat to Nottingham Forest on Saturday.
