Injured New Orleans Saints tight end Jimmy Graham's status is uncertain for Sunday against the Buffalo Bills, a source said Monday. ESPN is reporting that Saints TE Jimmy Graham, who left New Orleans Week 6 game at New England with a foot injury is uncertain for this week’s game against the Bills, despite having a week off this past weekend with the Saints on the bye. Had the Saints played on Sunday, the source said Graham might have been sidelined and could still be sidelined this Sunday. The Saints will test Graham's foot injury this week and determine whether he is healthy enough to play. Sources told ESPN that Graham likely would’ve been sidelined this past weekend if New Orleans had a game on their schedule. On the heels of their win over Miami Sunday, the Bills now prepare for the daunting task of trying to get a win in one of the toughest places to play in the league, the Superdome in New Orleans.
