English Premier League strugglers Sunderland face a month without former France international defender Anthony Reveillere who has a calf injury.
The 35-year-old fullback -- capped 20 times -- suffered the injury during the warm-up prior to Sunderland's crucial 1-0 win over fellow north east English side Newcastle last Sunday.
Reveillere, who signed for Sunderland in late October, will be replaced by either Irish international centreback John O'Shea, who filled in against Newcastle, or specialist fullback Billy Jones for Friday's match against fellow strugglers Hull.
Sunderland are presently 14th, four points above the relegation places while Hull are deeper in trouble second from bottom with no wins in their last 10 games and losing six of the past eight.
