METAIRIE, La. – Drew Brees is no longer on the New Orleans Saints' injury report. But the guys protecting him are pretty banged up.

Three of New Orleans’ starting offensive linemen are on the injury report, leaving their status uncertain for Sunday’s game at the Philadelphia Eagles.

Left tackle Terron Armstead missed practice for the second straight day Thursday with a knee injury. Left guard Tim Lelito missed practice with a back injury Thursday after he had fully practiced on Wednesday. And right guard Jahri Evans was limited in practice for the second straight day as he recovers from arthroscopic knee surgery that sidelined him for the last two games.

We should get a better feel Friday for whether or not any of these guys have a chance to play.

If Armstead can't play, he would be replaced by rookie first-round draft pick Andrus Peat, who has played in just 27 snaps this year, mostly as an extra tight end in jumbo packages. Veteran guard Senio Kelemete has been filling in for Evans and veteran guard Mike McGlynn could fill in at left guard, if needed.

The good news for New Orleans is that the Eagles’ pass rush hasn’t been very dynamic this year. According to a formula used by ESPN Stats & Information to measure pass-rush effectiveness based on the number of pass-rushers on each play, the Eagles rank last in the NFL, having controlled the line of scrimmage on 45 percent of opponents’ dropbacks.

Also on the Saints’ injury report Thursday: Punter Thomas Morstead (quad) did not practice, while safety Jairus Byrd (knee) and cornerback Keenan Lewis (hip) were limited.

Wide receiver Marques Colston and defensive tackle Kevin Williams both returned to full practice Thursday after getting a veterans' day of rest on Wednesday.
