                     === Panthers' Stewart has torn MCL ===
 Charlotte,  NC  ( -  Carolina Panthers running back Jonathan
 Stewart was diagnosed with a medial collateral ligament tear in his right knee
 Monday,  an  injury that could  sideline him for  the remainder of the regular
 Stewart exited Sunday's 31-13 loss at NFC South-rival New Orleans in the third
 quarter after taking a shot to the knee from Saints cornerback Keenan Lewis at
 the  end of a  catch. The Panthers have already ruled the six-year veteran out

 fullback  Mike Tolbert capable of contributing as well. Those two received the
