Carolina Panthers running back Christian McCaffrey will miss at least another three games after he was placed on injured reserve Saturday.
McCaffrey has already missed the last two games with a hamstring injury.
Coach Matt Rhule was optimistic the Pro Bowl back would return this week after practicing last week on a limited basis, but McCaffrey was limited again Wednesday and didn't practice on Thursday or Friday.
Rookie Chuba Hubbard again will be the starter for Sunday's game against the Minnesota Vikings.
McCaffrey missed 13 games with three different injuries last season after the Panthers made him the highest-paid back in the league with a four-year, $64 million extension.
