HITC Sport understands Blackburn are closing in on defender deal.
League One promotion hopefuls Blackburn have been chasing Bell all month and, after having their first bid rejected, they have now had their second of bid of £300,000 accepted by Fleetwood.
Rovers boss Tony Mowbray has made a new left-back one of his top priorities during the transfer window and Bell has been his top target.
A number of clubs have been monitoring the former Birmingham City defender, but Blackburn have moved quickly to try to bring Bell to Ewood Park.
Bell's future has been the subject of speculation since the transfer window opened, with the defender out of contract in the summer and already having turned down a new deal at Highbury.
The 23-year-old has made over 100 appearances for Fleetwood since joining them on a free transfer from Birmingham City in the summer of 2015
Fleetwood were reluctant to lose Bell, but they are ready to cash in on him rather than risk allowing the defender to run down his contract and leave for nothing in the summer.
