Town are reported to be amongst a host of clubs showing interest in out-of-contract Rotherham striker David Ball.
According to the Blackpool Gazette, the 29-year-old is on Blackpool’s radar but with Bradford, where he spent most of last season on loan, also keen along with the Blues, Sunderland, Lincoln City, Tranmere Rovers along with a number of League Two teams.
Whitefield-born Ball started his career with local club Manchester City and spent time on loan at Swindon while with the Cityzens.
In 2011 the 6ft-tall frontman moved on to Peterborough on a permanent basis without having made a senior appearance for City.
After a spell on loan at Rochdale, Ball left for Fleetwood where he spent a five-year spell prior to moving to Rotherham in the summer of 2017.
While Town have already signed one striker this summer, James Norwood from Tranmere, Blues boss Paul Lambert is understood to want a second with former loanee Will Keane, a free agent following his release by Hull City, among those in his thoughts.
Lambert would almost certainly be after a striker with a better recent scoring record than Ball, who netted only five times in League One last season as the Bantams finished bottom.
However, he netted nine goals the previous year as the Millers went up via the play-offs, while he scored 14 a season earlier as Fleetwood also reached the League One play-offs.
The striker is the second released Rotherham man called Ball to have been linked this summer with defender Dominic Ball having been mentioned in connection with the Blues last week.
