Philadelphia 76ers coach Doc Rivers said that he is feeling a lot better, but he is not sure if he will return to the court.

Rivers said before Philadelphia practiced Tuesday afternoon that he didn't want to give false hope, but he knows that he is feeling a lot better. I will stop there.

The 76ers lost the first game of the Eastern Conference semifinal against the Miami Heat because of a concussion and facial injury suffered by center Joel Embiid.

According to Adrian Wojnarowski of ESPN, Embiid could return as soon as Game 3 on Friday or Game 4 on Sunday back in Philadelphia.

Four years ago, Embiid missed three weeks after undergoing surgery to repair a left facial fracture, including missing the first two games of Philadelphia's first-round series victory over the Heat.

The other members of the 76ers are expected to play in Game 2.
