Northampton have signed former Millwall winger Chris Hackett on a two-year deal starting at the beginning of August.
The 29-year-old midfielder had a short spell at Hearts, but spent most of his career at Millwall, scoring six times in 145 appearances for the Lions, before loan periods at Exeter and Wycombe last season.
Hackett started his career with his hometown club, Oxford, making his debut in 2000.
Cobblers boss Aidy Boothroyd told the official website: "Chris is a signing I am very pleased to make.
"He is someone I have tracked for a while and is another player who has played regularly at a higher level. He has a very good pedigree, and he will bring experience, pace and guile to the squad.
"I am very much looking forward to working with him and like the other players who have come in so far this summer, I am sure he will prove a good signing for us."
