Town skipper Luke Chambers is reportedly a target of MLS side the Chicago Fire.
According to the Daily Mail, the Fire are keen to add a central defender to their squad with Chambers said to fit the bill both from a playing and financial perspective.
Chambers is out of contract with the Blues in the summer but with the club having an option to keep him for a further season.
Manager Paul Lambert recently said he had spoken to his captain, who joined Town on a free transfer in 2012 after leaving Nottingham Forest, about staying at Portman Road beyond this season, stating that Chambers, 33, and Cole Skuse, 32, both have a massive part to play in the club going forward.
He added that owner Marcus Evans is also set to talk to the one-time Northampton defender about his future.
