Captain Garry Flitcroft was another victim of the game after crashing out with a shoulder injury.
Both are expected to miss out on the trip to Sofia and probably the visit of Tottenham, too.
“Losing Dwight is a big blow for us. He has had a recurrence of his hamstring injury and Garry Flitcroft has damaged a joint in his shoulder,” explained Souness.
"I think both players will miss the next two games - certainly Dwight will, and that is undoubtedly a blow for us.''
