I am of the opinion that this tear did not happen while shagging balls in BP the other night. I suspect that the injury was gradual and as such may have been present when he was brought on.
I am not an expert, however. I have just suffered through meniscus pain for years and then had surgery. Rehab for me took over 4 months. But my meniscus looked like an inverted bottle cap when scope photos were taken. Mine was worse, I guess.
Still, 3 weeks sound very optimistic to me. 6 weeks? I don't know about that either.
This sucks.
Doc, what can you add?
