The Saints' top two receivers, Marques Colston and Joe Horn, missed practice again Wednesday and were listed as questionable for Sunday night's game at Dallas.

Reggie Bush also sat out with a mild shoulder sprain but was listed as probable, while starting right offensive tackle Jon Stinchcomb also was listed as probable after missing practice with a stomach virus.

Defensive end Will Smith, who missed last Sunday's game with a bruised right knee, returned to practice, but the Saints again listed him as questionable.

The Saints also listed Scott Fujita as probable with a sore ankle, although he practised.

Horn started on Sunday, but on his first catch in the first quarter he aggravated a nagging groin injury that had kept him out of two previous games. He did not return to action.

Colston, who has not played for nearly three full games, said Wednesday that he is making progress on his sprained left ankle.

He said he has the strength to push off and play, but that he would be doing so in pain and possibly risking further injury. For that reason, trainers are taking a conservative approach with him as the Saints, leading the NFC South, make a push for the playoffs.

``For a while it was getting pretty frustrating, but you've got to realize it's something that comes with this game,'' Colston said. ``You just try to keep a positive attitude and get back as soon as possible.

``Physically I can probably get out there and push through some of the pain, but on Wednesday that really doesn't help too much, so we're just trying to be smart about it,'' he said.
