The Cobblers have signed right-back Brendan Moloney on loan from Yeovil Town until the end of the season.
The Irish defender has been recruited in time to be available for selection for the home game against Southend United on Saturday (3pm kick-off).
Moloney began his career as an academy player at Nottingham Forest and was given his senior debut at the City Ground by former Northampton manager Colin Calderwood.
He had loan spells with Chesterfield, Rushden & Diamonds, Notts County and Scunthorpe United before a permanent move to Bristol City in January 2013.
Moloney played 58 times for City in an 18-month spell before transferring to Yeovil, for whom he has played seven times this season.
Moving to the Cobblers, however, means Moloney will not be involved in Yeovil’s high-profile FA Cup third-round clash with Manchester United at Huish Park, although he insists finding first-team football was a bigger priority.
“You don’t get too many opportunities to be involved in games like that, but my main priority was to get out and play some football,” he said.
“Obviously it’s a disappointment but that’s the way football is. It’s on television so I’ll be tuning in to it.”
Moloney replaces Danny Alfei as the squad’s loan right-back following the Wales under-21 player’s return to Swansea City after his own deal was cancelled.
“It happened pretty quickly over the past day or so and I trained for the first time with the (Northampton) squad today (Friday),” he said.
“There’s a positive atmosphere around the squad, everyone seems to be looking forward to the New Year and the games coming up.
“I like to get forward and provide crosses but first and foremost I will make sure that I’m defensively solid.”
