Cardinals' Marvin Harrison Jr. (concussion) will play vs. Chargers - ESPN

TEMPE, Ariz. — Arizona Cardinals rookie wide receiver Marvin Harrison Jr. will play Monday night against the Los Angeles Chargers after clearing the NFL's concussion protocol, coach Jonathan Gannon said Saturday.

Harrison was a full participant in Friday's practice after being limited on Thursday, Arizona's first practice of the week, while wearing a yellow non-contact jersey.

Gannon said Harrison had a «good week» of practice and is «ready to go.»

Harrison left Sunday's loss to the Green Bay Packers in the second quarter after his head collided with the thigh of Packers linebacker Isaiah McDuffie with 6:28 left in the half. Harrison was helped off the field by Cardinals trainers and, after getting evaluated in the blue injury tent on the sideline, left the field and was escorted to the locker room by a team of Arizona trainers and doctors.

He was ruled out shortly after the second half began.
