The Carolina Panthers released veteran running back Jonathan Stewart on Wednesday, and head coach Ron Rivera said people shouldn't assume the obvious with regards to Stewart's replacement. Jonathan Stewart Panthers replacement news Rivera made it clear Thursday at the NFL scouting combine that the decision to cut Stewart — Carolina's all-time leading rusher after ten years with the team — was a difficult one for him. The Panthers saved around $3.7 million in salary cap space with the move. Stewart, who will be 31 on March 21, was coming off one of his worst seasons statistically on an offensive line general manager Marty Hurney considered one of the top five in the league. Stewart averaged a career-low 3.4 yards per carry (680 yards on 198 carries), and his total yards were his fewest since 2013, when he was limited by injuries. The only other two running backs who had lower averaged yards per carry this season despite racking up 150 carries or more were Adrian Peterson and Ameer Abdullah, per ESPN Stats & Information. People may expect the Panthers to find a running back who is known for power runs, as this was Stewart's style, but Rivera said this may not necessarily be exactly what his team is seeking now. The coach said he'd like to find a pass rusher with a dynamic skill set to work in tandem with pass-catching back Christian McCaffrey. Among the other positions Carolina is urgently seeking are receiver, edge rusher, guard and safety. The NFL scouting combine began Tuesday at Lucas Oil Stadium in Indiana, and will end on Monday (March 5). Stewart finishes his ten-year career in Carolina with 7,318 yards.
