"He did have a concussion," Kubiak said. "He's obviously in the protocol. He's doing great today. He's out. Rode the bike today. Doing great, but he is in the protocol right now."
The 'protocol' is a process that all concussed players must pass through in the NFL. Johnson was knocked from the game after coming down with a 21-yard catch late in the fourth quarter
"Obviously it will be an end of the week decision because he's gotta go through the process," Kubiak said. "But I think after the game, talking to him, seeing where he's at today, obviously he's doing really well. I would expect the prorgress to go pretty quickly if it goes like it has the last 24 hours."
The Texans will have Tuesday off. They return to practice on Wednesday.
