Per NFL.com - Tim Hightower will be getting the bulk of the carries this weekend.
From the article...
Tim Hightower, not C.J. Spiller will get the bulk of the workload in the Saints' backfield with Mark Ingram on injured reserve.
NFL Media Insider Ian Rapoport reported Sunday on NFL Network's GameDay Morning that theSaints will utilize Hightower in place of an injured Ingram, mainly because of their similar running styles......
"From what I am told, he struggled to grasp this offense -- something which was never the problem for him in Buffalo," Rapoport said. "They doubt some of the explosiveness that he has. At this point it seems to be a longshot that Spiller is on the Saints' team in 2016."
Spiller still has the potential to reach cash game value, but for the same price, it's smarter to pivot to Hightower.
