Town are reported to be among a number of clubs showing interest in Accrington Stanley striker Kayden Jackson.
According to HITC Sport, Rotherham and Peterborough have had bids turned down by the newly-promoted League One club for the 24-year-old, while the Blues and Preston have made enquiries.
Jackson, who scored 16 goals in 48 starts and one sub appearance last season, previously played for Paul Hurst, albeit briefly, at Grimsby during a loan spell in the first half of the 2016/17 season before the Blues boss moved on to Shrewsbury in the October.
Bradford-born Jackson started his professional career with Swindon following success in a 2013 Win a Pro Contract competition run by Samsung when a player with Albion Sports in the Northern Counties East League Division One.
While with the Robins, he had spells on loan at Swindon Supermarine and Oxford City, prior to stints with Tamworth, Wrexham and Barnsley before his loan with Grimsby and his permanent switch to his current club last summer.
Stanley are said to be after in excess of £1 million for 5ft 11in tall Jackson, who is contracted until the summer of 2019 and can play in wide roles in addition to operating down the centre.
