Barnsley are thought to be weighing up moves for James Coppinger, James Husband and Peter Clarke.
The Tykes, who have already snapped up former Rovers goalkeeper Ross Turnbull and trialist James Bailey this week, are revving up their recruitment drive ahead of the new season.
And they could add to Rovers fans’ growing frustration at their team’s lack of inward movement by making a move for yet more players with a Doncaster connection.
Barnsley are one of several League One and Championship clubs showing an interest in Coppinger, who yesterday confirmed that his 10-year career at Rovers was over.
Danny Wilson is known to be looking to strengthen his right midfield options - and Coppinger fits the bill.
After spending ten years at Doncaster, Coppinger would be well aware of the delicate nature of a potential switch across South Yorkshire.
But such a move would enable him and his young family to remain in the area and could appeal to the 33-year-old wideman.
The possibility of Husband joining the Reds is likely to be even more alarming and surprising for those of a Doncaster persuasion.
The 21-year-old was linked with a move to Hull City earlier this summer and the defender ultimately has ambitions of playing in the Premier League - so swapping one League One club for another would appear to be a sideways step.
However, Barnsley boss Danny Wilson is keen to bolster his left back options and is well aware that Rovers could be tempted to accept a cut price offer for the highly rated defender.
Doncaster boss Paul Dickov is working to a tight budget for the forthcoming season and could well choose to cash in on the youngster - if Barnsley meet Doncaster’s asking price.
Barnsley, meanwhile, have retained an interest in Clarke throughout the summer, despite the former Huddersfield captain spending time on trial at Rovers.
Clarke told The Star earlier this week he agreed a deal with Doncaster subject to John Ryan and Louis Tomlinson’s takeover going through - but was now waiting by the phone for a revised offer.
