Joel Embiid's game was off on Sunday during Game 4 between the Philadelphia 76ers and Toronto Raptors.

The Process was held to an underwhelming 11 points as his team fell 101-96 ​on their home floor. But once reporters were able to speak to Embiid after the game, his uncharacteristic performance had a very valid reason to it.

​​In the locker room after the loss, Embiid described what seemed like a rough night for the big man. He said he didn't sleep and was throwing up to the point he needed an IV for hydration on Sunday morning. 

Sixers' head coach Brett Brown said that he had received a text from Embiid at 6:20 a.m. saying that he didn't even know if he would be able to play in Game 4.

Embiid has been dealing with health issues for some time now, but it's about to get very inconvenient for the 76ers if it persists throughout the postseason now that they are tied with the Raptors going back to Toronto.

Philly fans can only hope he gets enough rest before Game 5 to give the 76ers another dominant performance.
