The Carolina Panthers might need some reinforcements at running back.
Jonathan Stewart (ankle), Mike Tolbert (knee) and DeAngelo Williams (quadriceps) all missed practice Wednesday due to injuries.
Although none were immediately signed, the Panthers did bring in four running backs for workouts and visits.
The Panthers auditioned former Denver Broncos running back Lance Ball, former Clevleand Browns running back Brandon Jackson, former Baltimore Ravens and Miami Dolphins running back Jalen Parmele and former Chicago Bears and New York Jets running back Kahlil Bell.
None were immediately signed, though.
