Metairie, LA -- (Sports Network) - The undefeated New Orleans Saints will be without cornerbacks Jabari Greer and Tracy Porter for Sunday's game against the Tampa Bay Buccaneers.

Greer (groin) and Porter (knee) did not practice all week along with running back Reggie Bush, who is questionable with a sore knee.

Starting free safety Darren Sharper is probable after taking full snaps on Friday despite a knee problem. Also ailing on the defensive side of the ball is defensive end Sedrick Ellis (knee), who is questionable after being limited in practice all week.

Wideout Lance Moore (ankle) has been ruled out for Sunday, though starting center Jonathan Goodwin (ankle) is likely to suit up.
