WHITE SULPHUR SPRINGS, W.Va. -- The New Orleans Saints’ injury list seems to have a revolving door on it. Every time two or three guys return to the field, two or three new guys go missing.

On Friday, running back C.J. Spiller, guard Tim Lelito and defensive end Akiem Hicks were absent for unspecified reasons. Coach Sean Payton declined to elaborate on any of them -- though he did indicate that Spiller’s absence was injury-related. Teams aren’t required to reveal injury information during training camp.

UPDATE: A source described Spiller's absence as nothing more than a day of rest.

It's too early to get worked up over any of the injuries until we see how long they linger. But all three of those guys are awfully important. Spiller is expected to be one of the most dynamic playmakers for a Saints offense that needs new go-to guys to emerge after parting ways with Jimmy Graham, Kenny Stills and Pierre Thomas in the offseason. It was a shame we didn't get to see him in action during the scrimmage.

Players will be off Saturday before returning to the practice field Sunday evening. Here’s a rundown of some other notable injuries:
