Skipper Sol damaged ankle ligaments in a challenge with Ray Parlour in Sunday's semi-final against Arsenal and it was initially feared he would be out for the season.
He was with a specialist today (Thursday) and boss Glenn Hoddle revealed: "We're hoping Sol isn't as bad as we first thought. He is with the specialist and we're hoping for good news."
Steffen spent the night in hospital under observation after a shuddering collision with Bradford’s Andy Myers left the Norwegian hitman unconscious during the second half of Tuesday night’s clash at the Lane.
He was released yesterday and is now recovering at home. Thankfully there seems to be no long-term damage done although he is unlikely to feature at Sunderland and is a big doubt for Tuesday's visit of Chelsea.
Glenn added: "Steffen needs to be rested and given time to recouperate from being knocked unconscious."
Meanwhile, Glenn is preparing for the tricky trip to the Stadium of Light with little respite from the treatment room.
Of those players missing for Tuesday night's win against Bradford City only Ledley King has a realistic chance of returning on Saturday.
That means Sol, Steffen Iversen, Steffen Freund, Les Ferdinand, Darren Anderton, Chris Armstrong, Ben Thatcher and Mauricio Taricco are all missing.
The latest news on Sol Campbell and Steffen Iversen appears more positive.
