"Although he is doing everything he can to play against the Denver Broncos on Sunday, there is a good chance Texans receiver Andre Johnson will miss his second game of the season because of an ankle injury.

Johnson disclosed after practice Friday that an MRI this week showed new damage to the high ankle sprain he suffered in the second game of the season.

Johnson, who needs to average 142 yards in the last two games against Denver and Jacksonville to become the first receiver to have at least 1,500 yards in three consecutive seasons, will be a game-time decision.

"I'm trying to do everything I can to make sure I'm out there, pretty much like I have been for weeks," he said. "I've been banging it up for 10 or 11 weeks, and it's kind of taken a toll.

"I had something happen to it in the Baltimore game. We didn't think it could get any worse, but it has. I had an MRI, and things weren't the same. The past few MRIs were the same, but we found some change in this one."

If Johnson, 29, can't play, he'll be replaced in the lineup by Jacoby Jones (41 catches, 377 yards, three touchdowns), who would start opposite Kevin Walter (47 for 553 and five). Rookie Dorin Dickerson will become the third receiver."
