Philadelphia 76ers head coach Doc Rivers said no decision has been made on Joel Embiid's status for Game 1 of the Eastern Conference semi-finals in the NBA playoffs.

The top-seeded 76ers are set to open their second-round series against the Atlanta Hawks on Sunday with doubts over the fitness of All-Star Embiid.

Embiid suffered a lateral meniscus tear in his right knee during Monday's Game 4 loss to the Washington Wizards, forcing him to sit out Wednesday's Game 5 as the 76ers won 129-112 to clinch the opening-round series 4-1.

As the 76ers continue their championship bid against the fifth-seeded Hawks, Rivers was asked about MVP finalist Embiid – who missed 10 regular-season games due to bone bruising in his left leg – on Friday.

"He went through a lot of the stuff today," said Rivers. "He didn't do a lot of live stuff obviously, we're not gonna allow that yet.

"Nothing's changed. He's got to go through his treatment, but as far as when we were doing shooting and stuff like that, he looked great.

"It's too early [to rule him out]. I don't want to say one way or the other. We'll just find that out."

It has been a stellar season for Embiid, who has averaged career highs for points (28.5), field-goal percentage (41.3), three-point percentage (37.7) and free-throw percentage (85.9).

The 27-year-old has also been averaging 10.6 rebounds, 2.8 assists and a career-best 0.98 steals per game to lead the 76ers – eyeing a first NBA title since 1983 – to their first Eastern Conference championship since 2001.

Philadelphia team-mate Dwight Howard, gearing up for a reunion with former team the Hawks, added: "He looked good. His movement looked good and laterally, he was able to move around so he looked good.

"I think he should be ready to go. Now he can make sure he gets his body right and I don't want him to rush back or anything like that because we need him.

"We want to make sure we hold down the fort until he's back, but he looked great."
