CHARLOTTE, N.C. (AP) - Panthers coach Ron Rivera says the team has placed Jonathan Stewart on the physically unable to perform (PUP) list, meaning the veteran running back will miss at least the first six weeks of the season.
Carolina also placed guard Edmund Kugbila, the team's fourth-round draft pick, on injured reserve Tuesday with a knee injury and waived-injured defensive tackle Frank Kearse and wide receiver Joe Adams.
Stewart says his goal is to return for Carolina's Oct. 20 game against the St. Louis Rams.
Stewart hasn't practiced with the Panthers since undergoing offseason surgery on both ankles. He says his right ankle remains a problem.
The decision likely means more playing time for DeAngelo Williams, the franchise's all-time leading rusher, and opens a roster spot for either Tauren Poole or Armond Smith.
