CHARLOTTE, N.C. -- The Carolina Panthers will place quarterback Sam Darnold on injured reserve with a shoulder injury, which is believed to have occurred in Sunday's loss to the New England Patriots.
Carolina coach Matt Rhule said Darnold is expected to miss at least four weeks.
P.J. Walker, who played for Rhule at Temple and starred in the XFL before signing with Carolina last year, will get his second NFL start on Sunday when the Panthers (4-5) play at Arizona (8-1).
He won his first start last year, 20-0, against the Detroit Lions.
