Oft-injured Cincinnati Reds third basemen Scott Rolen will return to the lineup later this week from concussion symptoms where he will remain indefinitely until he his hurt again. "We will evaluate Scott on a daily basis and see how long he has to remain in," said Reds manager Dusty Baker. "I know this is frustrating for him. He usually has definitive word on a season-ending injury by this point in the season." Rolen says he hopes to be back to 60-percent as soon as possible.
