One of the two key veterans the Saints placed on the physically unable to perform list has returned.

Wide receiver Marques Colston is back on the field and going through warm ups on the second day of training camp.

Colston sat out all of the Saints’ summer workouts with an undisclosed injury.

On the flip side, veteran linebacker Dannell Ellerbe is sitting out the practice, working on the bike off to the side. Cornerback Brian Dixon, who’s on the non-football injury list, has done some work on the bike each of the past two days.

So far, Jairus Byrd has not been seen on the practice field, although the Saints have said they don’t consider his injury to be serious.
