Houston Texans wide receiver Andre Johnson has suffered a lung contusion.

He's regarded as day-to-day and isn't a lock to play in Sunday's game against the Buffalo Bills, according to coach Gary Kubiak.

"(The doctors) feel good about it. It looks like he's going to be fine," Kubiak said. "We're fortunate here and hopefully he'll be ready to go against Buffalo."

Johnson was taken to a hospital after he fell on the ball and coughed up blood against the San Francisco 49ers.
