The Texans will find out Monday if an MRI on Andre Johnson's left knee shows any serious damage. Johnson said he strained his posterior cruciate ligament and will be day-to-day heading into the big match-up with the Indianapolis Colts at Reliant Stadium on Sunday. "I'm a guy who never has injuries," said Johnson, who has started 63 of 66 games in his career. "To have Indianapolis coming in next week, that's a game you don't want to miss. I'm going to take it one day at a time and do what I need to do to get myself ready."
