CHARLOTTE, N.C. (AP) Panthers coach Ron Rivera says the team is awaiting the results on an MRI on running back Jonathan Stewart's right hamstring.

Rivera says the initial indications are not good.

While he doesn't know exactly how long Stewart will be out, Rivera says, ''if it's a hamstring - and every indication is that it is - it's going to be at least a week or two. We'll see how severe.''

Stewart injured his hamstring in the first quarter of Carolina's 47-26 win over San Francisco on Sunday.

Fozzy Whittaker, who ran for 100 yards on 16 carries in the win, will start Sunday against the Minnesota Vikings. Rivera says the team will activate Cameron Artis-Payne as a backup. He has been inactive the last two games for Carolina (1-1).
