Southampton boss Nigel Adkins has no new injury or suspension problems.
Guly Do Prado continues to struggle with a hamstring strain that has seen him miss the last two matches and is not expected to recover in time.
Dan Seaborne, Jonathan Forte and David Connolly are pushing for a return to the squad after recovering from minor niggles.
Midfielder Morgan Schneiderlin will again be absent with the knee injury he suffered against Walsall last Tuesday.
Tommy Forecast will continue on the substitutes' bench in the absence of back-up keeper Bartosz Bialkowski, who may require surgery on a knee injury.
It remains to been seen if Ben Reeves keeps his place in the squad after he was picked among the substitutes for the first time this season at the weekend.
Paul Wotton is a major doubt for Glovers boss Terry Skiverton.
The veteran midfielder suffered a hamstring injury five minutes into Saturday's 1-1 draw with 10-man Huddersfield and is unlikely to recover in time to face the club he made over 50 appearances for before signing for the Glovers.
Ed Upson replaced Wotton against the Terriers and is likely to take his place in the starting line-up at St Mary's.
Sam Williams is also pushing for a return to the XI after his 15-minute substitute appearance at the weekend, while loan striker Antonio German is pressing for his first start since signing on loan from QPR.
