SUNDERLAND have suffered their first setback of the season with winger Carlos Edwards ruled out for a month with a hamstring injury.

Edwards limped off during the midweek 2-2 draw at Birmingham after a 60-yard run that almost created a goal for substitute Stern John - the stiker heading Edwards' cross against the bar.

Keane will reshuffle his side once again for Saturday's trip to Wigan with Dean Whitehead and Liam Miller both capable of playing wide right.
