Raburn left Thursday's Cactus League game with left knee discomfort, Nick Camino of WTAM 1100 reports. The initial description doesn't sound too serious, until you remember that Raburn had arthroscopic surgery on his left knee in September. He wasn't restricted at the start of spring training but it's still a bit worrisome that the same knee is bothering him. If healthy, Raburn will likely make the Opening Day roster, though he may have his $2.5 million salary to thank for that.
