Will Hoskins (knee) and Craig Mackail-Smith (Achilles) remain on the treatment table, but the Seagulls’ summer acquisition from MK Dons has been ruled out of the game at Elland Road.
Albion head coach Oscar Garcia told seagulls.co.uk, “Adam Chicksen is not able to play as he is injured but all the other players are available for tomorrow. He has a little injury and maybe next week he will be fit enough to play.
“As everyone knows, Craig Mackail-Smith cannot play for a long time and Will Hoskins also. It’s difficult to say when Craig will be fit but we have to see each day how his recover is going.
“I would obviously prefer to have all the squad available to play so I could decide our best eleven but it is football, these things happen at times and you have to adapt.”
David Lopez and Matthew Upson are in the frame to make their first appearances following their return to the club during the summer.
Leeds United boss Brian McDermott will be without the suspended duo of El-Hadji Diouf and Rudolph Austin, who were both sent off in last season's corresponding fixture which Albion went on to win 2-1.
Triple summer signings Noel Hunt, Matt Smith and Luke Murphy are all available for selection.
