Running back Jonathan Stewart has announced he is retiring from the NFL.
Stewart, who spent last season with the New York Giants, signed a one-day contract Tuesday with the Carolina Panthers. Stewart spent 10 seasons with the Panthers and is the franchise's career leading rusher with 7,318 yards.
He was released by Carolina prior to last season in a salary cap move and signed a one-year deal with the Giants. However, injuries limited him to six carries in three games.
