Terrmel Sledge was taken off the active roster today with pain in his left knee. He will be returning to the US within the next couple days for an evaluation.
The team trainer told reporters that it was not a sudden development and that the pain had been increasing over time until it got so bad that he missed Thursday's game against the Yomiuri Giants. The trainer also mentioned that Sledge had surgery on his left knee back in 2008, before arriving in Japan.
