Northampton have signed Gary Deegan on a one-year deal after the Dublin-born midfielder completed a successful trial period with the club.
The 25-year-old Irishman had spells with both Coventry and Hibernian before arriving at Sixfields and boss Aidy Boothroyd has been impressed with his performances so far.
"Gary is a player with a good pedigree and I am pleased to have signed him," said the Cobblers manager.
"He will give us bite and aggression in the midfield and he is a good blend with the midfielders we already have here.
"He has settled in well during pre-season both on and off the field and he is another good addition to the squad."
