ARLINGTON -- The Angels' plans of getting to the postseason healthy and re-energized might have taken a hit when center fielder Gary Matthews Jr. left Wednesday's game after the first inning.

The good news is that it apparently was unrelated to the sprained right ankle that had kept Matthews sidelined for 10 games.

Matthews, who was favoring his left leg as he came off the field, was examined by Rangers team physican Dr. Keith Meister and found to have an irritated left knee. He will be reevaluated when the team returns to California for a weekend series in Oakland starting on Friday night.

Hopefully (for the angels sake) it isn't serious

Isn't he out for the rest of the season?
