The Philadelphia 76ers are holding their collective breaths right now as they await the latest update from Joel Embiid's knee injury. It seems everything is still in the dark after Embiid left early in Game 4 against the Washington Wizards on Monday and did not return.

When asked by reporters for an update on Embiid after the game, Sixers coach Doc Rivers said even he himself doesn't know anything.

It could be that Rivers was talking the truth or he was just in no mood to talk to reporters after they lost to the Wizards, 122-114. He, however, said Embiid will most likely get an MRI on Tuesday.

Embiid tried to dunk in the first quarter but got challenged by Wizards center Robin Lopez, making the Sixers big man land hard on his tailbone. But when he got back up, it was evident he was feeling some pain in his knee. He quickly exited the game, tallying eight points and six rebounds.

Embiid's absence was too much for the Sixers as they struggled to fill his shoes. After all, the dominant center has been producing MVP numbers all season long, including a postseason career-high 36 points in their convincing Game 3 win.

Without the four-time All-Star, the Sixers will have to lean heavily on Dwight Howard and perhaps get some spot minutes from Mike Scott and Paul Reed. As you can see, the team doesn't have much on the frontline cupboard.

Joel Embiid has little time to recuperate as Game 5 is set on Wednesday.
