Mina Kimes explains why she is picking the Chargers to take home a win over the Cardinals in Week 7. (0:41)

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 Thursday, Arizona's first practice of the week, while wearing a yellow noncontact 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 hit the thigh of 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, left the field and was escorted to the locker room by a team of trainers and doctors.

He was ruled out shortly after the second half began.
