Martyn Waghorn is poised to leave Rangers and return to England after the Ibrox board accepted a bid from Ipswich Town.
Sunderland were also interested in striker Waghorn, a Wearsider who started his career at the Stadium of Light.
Simon Grayson has been searching for firepower after losing Jermain Defoe to Bournemouth.
But Ipswich have agreed a fee, thought to be in the region of £1million, for the 27-year-old.
Waghorn, a former England U21 international, moved to Scotland from Wigan in 2015 and helped Rangers back into the top flight of Scottish football.
