"[Wallace] had some knee soreness [so Thursday he] went to the doctor and had MRI. It shows he has a torn meniscus," head coach Brad Stevens said "The next step for him will be determined in the next couple of days, but obviously we want to prioritize his health."
Shutting Wallace down is a no-brainer, because for one, the Celtics aren't exactly looking to win games currently. But also, playing on a torn meniscus would totally stink. Because with the Celtics firmly in lottery position, there's no need to play with any discomfort.
Wallace was dealt to the Celtics from the Nets in the offseason, and has two years and about $20 million left on his deal. And now he'll be coming off a pretty significant knee injury for next season. It'll be interesting to watch if he remains with the Celtics, or if maybe there are buyout negotiations at some point in the future.
