Dominic Matteo is having tests today on the hamstring injury which cut short his Leeds comeback at Bolton.
Matteo, who returned from a groin injury to replace Ian Harte at left back, lasted only 44 minutes before suffering a hamstring strain and making way for Harte.
Leeds are hopeful that Eirik Bakke, shaken by a sixth-minute challenge by Paul Warhurst which led to him being replaced by Jason Wilcox, will be fit for Saturday's trip to Southampton.
Harry Kewell (back) and Seth Johnson (dead leg), who failed fitness tests ahead of the Bolton clash, could also be back to face the Saints while Danny Mills will be available again after serving a one-match suspension.
The injuries to Matteo and Bakke are a further setback for Leeds who were already without Olivier Dacourt, Lucas Radebe and Michael Bridges.
