Southampton will be without goalkeeper Kelvin Davis for the FA Cup trip to Northampton.

Davis suffered a groin injury during Tuesday night's 3-1 win at Hartlepool and could be sidelined until the new year, so Polish understudy Bartosz Bialkowski gets a rare chance.

Boss Alan Pardew will have to make at least one other change to his starting line-up as on-loan Preston defender Neal Trotman does not have permission to play in the competition, so Wayne Thomas or Chris Perry will step into the back four.

Chelsea youngster Jacob Mellis, who has been limited to a place on the bench recently, is also ineligible.

Midfielder Joseph Mills could return from illness but striker Marek Saganowski is sidelined after suffering a knee injury in training last week.

Northampton defender Chris McCready has been added to their injury list.

McCready injured his hamstring in the closing stages of the 2-1 defeat at Aldershot in midweek and is set for a fortnight on the sidelines.

Fellow centre-half Dean Beckwith remains out with the same injury but the Cobblers are hopeful Danny Swailes will be granted permission to make his debut after signing on loan from MK Dons.

On-loan Middlesbrough full-back John Johnson is a doubt to feature thanks to yet another hamstring injury while forward Adebayo Akinfenwa is also a doubt after limping off against the Shots with a sore knee.

Courtney Herbert and Abdul Osman remain out with back injuries, while winger Liam Davis has suffered a setback in his recovery from a broken foot and will be out for another three weeks.

Peter Crouch, Kevin Phillips and Jamie Redknapp were on the scoresheet the last time the Saints travelled to Sixfields for an FA Cup tie in 2005.
