Philadelphia 76ers center Joel Embiid traveled with the team to Atlanta and is probable for Monday's game against the Hawks while Ben Simmons will remain out with knee soreness, a source told ESPN's Ramona Shelburne.

Embiid (back soreness) and Simmons both missed Saturday's loss to Denver -- in which the Sixers had just seven players available because of injuries and health and safety protocols.

Coach Doc Rivers explained Saturday why both stars were held out of the game.

"Ben, in the Brooklyn game [on Thursday], had some knee stiffness, and so we almost probably knew after the game that he wouldn't play tonight," Rivers said. "And then Joel started complaining about his back over the last, at the start of yesterday.

"We didn't know if he was playing or not. But honestly, with the minutes we would have to ask, it would be insane to play him tonight."
