Republic of Ireland defender Enda Stevens could make a return to action for Sheffield United away to Southampton on Sunday. 

The left-sided defender has been nursing a knee injury and has not played since the 4-1 defeat at Stamford Bridge at the start of November. 

Stevens, along with Ethan Ampadu and Lys Mousset all resumed training this week, and provided they come through Saturday's session unscathed, manager Chris Wilder will be able to call on them at St Mary's. 

"They've all trained this morning, which is good news for the group," said the Blades boss. 

"They all added various minutes to the session and took part one way or another, so we'll monitor them over the next 24 hours and hopefully they come through the next training sessions and are on the coach to Southampton. They all have a chance of playing." 

United currently occupy the bottom spot in the table and have struggled defensively all season. If Ampadu and Stevens are fit to play, it will give Wilder a welcome selection headache. 

"It has been disruptive, particularly in that left centre-half spot, and Enda has been a mainstay for us. To miss an experienced player at a time when we need experienced players has been disappointing."
