Tampa Bay closer Troy Percival has decided not to have surgery and hopes to resume throwing off the mound in four or five days, according to The Associated Press. Percival damaged cartilage in his right knee while fielding a bunt against Oakland on Thursday. He may have surgery after the season ends. "Without it, it's very feasible it's two weeks," Percival said. "When I'm good to go, I'll be out there. I don't think it's going to get any worst, any better."
