After missing practice on Wednesday and Thursday, New Orleans Saints All-Pro tight end Jimmy Graham (pictured) returned to practice Friday on a limited basis. He is listed as questionable for Sunday's home matchup with the Buffalo Bills.

Graham is nursing a foot injury he suffered in Week 6 against the New England Patriots. New Orleans head coach Sean Payton was vague when asked about Graham's status, not talking to the media about his star tight end's status.

Running back Mark Ingram had missed the last several weeks of practice with a turf toe injury, but returned on Friday. Like Graham, it was on a limited basis, and like Graham, he is listed as questionable.

Even if Ingram is healthy enough to play, there is question as to whether he would be activated to the 45 man gameday roster. Undrafted rookie Khiry Robinson has played much better than Ingram this year. Fellow running backs Pierre Thomas and Darren Sproles are always active if healthy, and second-year back Travaris Cadet is a heavy part of New Orleans special teams unit.

Two other key starters are listed as questionable. Starting right tackle Zach Strief (ankle) and start defensive end Cam Jordan (ankle).

Three Saints are officially OUT for Sunday's game. Safety Roman Harper (knee), cornerback Rod Sweeting (hip), and defensive end/tackle Tyrunn Walker (knee).

Wide receiver Lance Moore (hand), who practiced this week for the first time since Week 3, is probable, as is starting free safety Malcolm Jenkins (back).

Buffalo will likely be without one of it's more talented players in running back C.J. Spiller (pictured), who continues to be hampered by a nagging ankle injury. Linebacker Manny Lawson is also listed as doubtful for the Bills.

Buffalo owns the NFL's 5th best rushing attack, thanks to Spiller and veteran Fred Jackson. Jackson, a team captain, will likely get the bulk of the touches Sunday, though he's officially listed as "probable" with a mild knee injury.

Another Bills captain listed as "probable" is former LSU defensive tackle Kyle Williams, who is dealing with an achilles.

Bills starting quarterback EJ Manuel will miss his second straight game with a sprained LCL. Thad Lewis will start again in his place, with Jeff Tuel as the primary backup, and newly signed veteran Matt Flynn playing 3rd string.

New Orleans (5-1) will host Buffalo (3-4) at the Mercedes-Benz Superdome this Sunday. Kickoff is set for noon. Catch all the action, including the postgame show, and "The Point After" with Bobby Hebert, on ESPN1420.
