Under that designation, Benson has to sit out for eight games, but can return to practice after six weeks.
"We feel that he can come back," coach Mike McCarthy said. "A foot sprain is definitely a tough injury to come back from, but within that time frame we feel that he definitely has a chance."
Benson injured his foot after being tackled Sunday against the Colts.
McCarthy says RB Alex Green will get the first carries in Benson's absence since he is further along than James Starks who hasn't played in a game this season while recovering from a turf toe.
