The two Blues defenders have been sidelined with hamstring injuries in recent weeks but have now recovered and are expected to be named in manager Alex McLeish's squad for the match against the Black Cats at St Andrews on Saturday afternoon. "Franck Queudrue and Stuart Parnaby are available again so we've got a couple of full-backs back, although I see Franck's role this season more at centre-half," McLeish has said. "We have been very short of full-backs this season and it is nice to see a couple of faces back."
