Both sides are looking for a second successive victory and a larger gap above the relegation zone, after a win for 18th-placed Cardiff City on Tuesday night.
Newcastle United sit 15th, seven points clear of the bottom three, while Southampton are one place and two points below their hosts but have a match in hand.
Team news
Newcastle are only without long-term absentees Florian Lejeune, who underwent a successful knee operation this week, and Sean Longstaff (also knee).
Southampton's Mario Lemina (abdominal) is back in training, although this match may come too soon for him, while there are also doubts over Jannik Vestergaard (groin).
Alex McCarthy, Matt Targett and Charlie Austin have minor problems and face late fitness tests but Yan Valery (cramp) is fit to play. Michael Obafemi (hamstring) is in individual training.
