Full-backs Fabian Wilnis and Jay McEveley are doubts ahead of Sunday's East Anglian derby with Norwich City (KO Noon). Wilnis limped off during last night's 2-2 draw against Southampton with an ankle injury, while McEveley was hampered by his foot problem during the second half.
Wilnis could be out for a number of weeks with the problem picked up just before half-time. McEveley hurt his foot in Saturday's game at Sheffield United and was a doubt ahead of Southampton's visit.
Spaniard Sito will be available for the Norwich game after completing his one-match suspension and will take over from Wilnis. If McEveley fails to make it Matt Richards will take over on the left side of the defence.
