The Carolina Panthers officially placed quarterback Sam Darnold on injured reserve Friday because of a shoulder injury.
According to Darin Gantt of the Panthers' official website, Panthers head coach Matt Rhule said earlier this week that Darnold is expected to miss four to six weeks. Placing Darnold on IR guarantees he will be out for at least the next three weeks.
P.J. Walker is in line to start at quarterback for the Panthers on Sunday against the Arizona Cardinals. Carolina has also signed Matt Barkley and Cam Newton as insurance.
