New Orleans running back C.J. Spiller will miss the season opener against Arizona, according to the NFL Network’s Ian Rapaport.

Spiller underwent a minor arthroscopic procedure on his knee early in training camp, and he’s missed the rest of camp recovering.

Initially, the Saints targeted a Week 1 return, but Rapaport’s report indicates that Spiller needs a little more time. Rapaport also reported that Spiller should be good to go again for the Saints’ home opener against Tampa Bay the next week.

Spiller’s injury may have been indicated by the Saints’ decision to keep five running backs on the roster. New Orleans kept Mark Ingram, Khiry Robinson, Tim Hightower and Marcus Murphy in addition to Spiller.
