Nothing sad about it. This is a minor injury that can happen to any player, and at this stage of the season for the Sixers and for Embiid, both can benefit for some time off. Embiid has been exceptional in his first season, and his foot has held up really well. It is good for him to get some extended rest over the all-star break period. For the Sixers, they of course will be glad to tack on some losses for pick purposes, but they can also use the opening to feature Noel and Okafor and Saric more.
