27-year-old Southend United defender Luke Prosser, a promotion-winner himself with the Shrimpers last season, has joined Northampton on loan until the summer when his Roots Hall contract expires.
"The boys are doing fantastically well, if I can help it will be brilliant," he told BBC Radio Northampton.
"There was interest in the summer but I was contracted to Southend and they weren't willing to let me go, but as of late I've been limited to games so there was an opportunity for me to come here."
