Ipswich have made an approach to sign Alan Judge from Brentford.
The two clubs held talks on Friday and will continue to discuss a potential deal over the weekend.
Judge, 30, has entered the final six months of his Bees contract and has struggled to nail down a first-team place this season.
The Republic of Ireland international has made just four Championship starts this term and only seven since recovering from a broken leg.
Judge spent a year and nine months on the sidelines following a tackle from Luke Hyam against Ipswich at Portman Road in 2016.
