Reda Johnson will miss at least the next two games after being ruled out with an ankle injury.
Johnson took the knock at Charlton last month and sat out the home win over Brighton at the weekend. Now he is sidelined for this Saturday’s match with Derby at S6 and then the trip to Birmingham on February 19.
Dave Jones says he hopes to have Reda back for the home game with Palace on February 23.
Johnson has been an inspirational figure in Wednesday’s recent revival, combining his aggressive defensive play with scoring important goals.
