Aston Villa interim manager Kevin MacDonald has told the club's official site that Ciaran Clark had to play against Southampton in the Capital One Cup last night.
Clark played in the heart of Villa's defence against Southampton, as the Midlands side crashed out of the tournament.
Villa lost 2-1 to the Saints, and by doing so extended their winless run to five matches in all competitions.
And MacDonald said: "Ciaran Clark had to play.
"He needs to play games and to be fair Jose Crespo and Ciaran Clark defended well against Graziano Pelle, especially in the first half.
"Micah Richards was injured, he's got a little niggle. Joleon Lescott was injured. Micah's might depend on what happens with the FA disciplinary. If nothing happens, hopefully they'll both be available for Monday."
MacDonald was taking charge of his first game since Tim Sherwood was sacked earlier in the week, and he was unable to spark the side into life.
Villa fell 2-0 down to Ronald Koeman's side, with Maya Yoshida and Graziano Pelle getting on the scoresheet, and by the time they did pull one back through Scott Sinclair it was too late.
MacDonald's team selection for the tie was a divisive one, with many of their most skilful players - including Jack Grealish and Carles Gil - left on the substitutes' bench.
Whether MacDonald will have another chance to name a Villa line-up remains to be seen, with the side hoping to have a permanent manager in place by the time they play against Tottenham Hotspur on Monday evening.
