ST. LOUIS -- His Cardinals tenure interrupted by injury from its start, Luke Gregerson now faces another recovery. The reliever is expected to miss four to six weeks after undergoing arthroscopic surgery Monday to repair a torn meniscus in his right knee.
Gregerson said his knee "flared up" last month, shortly after he was placed on the disabled list with shoulder and elbow soreness. The pain worsened in the three weeks that followed, prompting an MRI that revealed a meniscus "lodged in the joint," the reliever said. Gregerson also missed time in Spring Training with oblique tightness, then began the season on the DL with a left hamstring strain.
