Kevin McNaughton is doubtful for Cardiff`s home clash against Watford but fellow defender Gabor Gyepes may return.
McNaughton, who moved into the heart of defence for Tuesday`s 2-1 win over Coventry, was promptly withdrawn at half-time suffering with the thigh strain that threatened his involvement in the first place.
But Gyepes may return from the sore back that ruled him out of the clash at the Ricoh Arena and last weekend`s 1-0 defeat at Leicester.
Striker Michael Chopra is definitely available again having served a two-match ban.
Cardiff have also received positive news that midfielder Joe Ledley could be back within the next three weeks after his double hip operation while captain Mark Hudson is also expected to return in mid-April after surgery on his ruptured ankle tendon.
Kelvin Etuhu will rejoin matters next week after his lengthy injury problems while Josh Magennis is also nearing a return following his broken leg. But full-back Miguel Comminges has been ruled out for the season having undergone an operation on his anterior cruciate ligament.
Will Hoskins will be fit for Watford.
The striker scored the Hornets' winner against Ipswich on Tuesday night but had to go off after appearing to injure himself in the process.
However, the problem turned out to be cramp so Hoskins is in line to keep his place alongside Heidar Helguson in attack.
Will Buckley will be in the squad having got two reserve games under his belt in the past week.
The winger has yet to make his debut since joining from Rochdale in January due to a thigh strain.
Boss Malky Mackay has no other injury worries as his side go in search of a first away win in five months.
