The Jaguars were active on the waiver wire Sunday and their moves included the addition of two running backs.
Additional backfield depth was needed as Ian Rapoport of NFL Media reports that the team has placed Alfred Blue on injured reserve. Blue is dealing with an ankle injury and can be designated for a return after at least six weeks on the list.
Ervin moved on to the Ravens last year and failed to make the team out of camp this summer. Ozigbo fell short of a Saints roster spot after signing with the team as an undrafted free agent earlier this year.
Alfred Blue handled 28 touches on 99 percent of Texans snaps back in Week 5 without Lamar Miller. D'onta Foreman (Achilles) could be active for the first time this season this time. Philadelphia ranks just 30th in aFPA to RBs. If Foreman is inactive, Blue would be a volume-based RB2.
