According to Carolina coach Ron Rivera, Luke Kuechly “had a good day” on Monday, less than 24 hours after the linebacker suffered a concussion during the Panthers’ season-opening win in Jacksonville.

Kuechly is now in the NFL’s concussion protocol. Until he passes all the steps, his status for Week 2’s game against the Texans will remain up in the air.

“There are steps to the protocol that he has to go through and every day is a different step. Today was to come in and see how he is, and he’s fine. Tomorrow, he’ll go through the next step which I think is taking the baseline test and then he’ll be examined by the doctor,” Rivera said. “Today, the only thing I was told is that he was okay and he will continue the protocol as each day goes.”

Kuechly was injured shortly before halftime while attempting to make a tackle on Jaguars’ running back T.J. Yeldon. Kuechly, who led with his head, fell, tried to get up and then fell again.

Trainers helped him walk straight to the locker room after the two-time Pro Bowler shouted words of encouragement to his teammates staying on the field.

Rivera said Kuechly will be in the game plan as the Panthers get ready to host Houston, but six days before the home opener, it’s impossible to tell if he’ll be in that game.

“I don’t know the severity of it or how you’d grade it. The fortunate part is that he was able to get into the locker room on his own and he went through the protocol immediately and I saw him today and he looked like Luke to me,” Rivera said.

“We’re not going to put Luke out there until he’s ready to go. We’re going to go through the protocol the way it’s designed. That’s what we’ve done with all of our players. When each step is clear, then we’ll put him back on the field. Until then, he’s not going to play.”
