HOUSTON -- Texans receiver Andre Johnson expects to play on Sunday against the Ravens after missing last week's game because of a concussion.

Johnson says he finished the league's concussion protocol and has been cleared to return. He was injured after being hit in the head by Jaguars linebacker Telvin Smith on Dec. 7.

Johnson thinks he may have lost consciousness for a few seconds after the hit, but says that the helmet-to-helmet blow didn't scare him.

"It wasn't scary. I think it was more scary for other people than it was for me," Johnson said. "... Everybody else who saw it said it was a scary moment for them. I watched the play. Even after it happened, I didn't feel nervous or anything. It's a part of football. It happens. I've seen it happen several times. Just have to move on from it."

Johnson added that he felt like he blacked out for a moment, but remembers everything.

After he got up and went to the sideline, Johnson said he felt "fine." He said he had headaches last week.

"I think the biggest part is just being smart about the situation. That's why I didn't play last week; I was cleared to play," Johnson said. "I think it's more about just being smart about the situation. You have to communicate how you feel. That's pretty much it."
