Carolina Panthers linebacker A.J. Klein doesn’t think he had concussion

Carolina Panthers linebacker A.J. Klein believes his headaches were symptoms of a previous illness and not a concussion, but he’s still in the league’s concussion protocol.

Klein was set to meet with the independent neurologist Thursday as he’s continued to progress through the protocol.

“I wasn’t feeling well throughout the week leading up to Tampa,” Klein said. “I was fighting off some sickness. Obviously the day of the game didn’t feel too well either as far as sickness. But any time you have a headache or anything, you have to report it.

“I thought it was more about sickness, and just as a precaution they put me in the protocol to make sure everything’s right and we’re good to go this Sunday.”

Klein said he anticipates being ready for Sunday so long as he’s cleared. Klein filled in nicely for Luke Kuechly as Kuechly missed 14 of 16 quarters with a concussion.

Klein was limited in Thursday’s practice along with tight end Richie Brockel (hamstring) and offensive lineman Amini Silatolu (ankle), who should be active this week.

Kuechly and receiver Jerricho Cotchery (ankle) were full participants for a second consecutive day.
