General manager Elton Brand said Wednesday that Embiid was expected to play in the postseason, but added it was "possible" the 7-foot center wouldn't be ready for the first game.
Embiid was inactive for 14 of the 76ers' final 24 regular-season game with the knee pain described on injury reports as tendinitis.
"We're planning on him playing", Atkinson said.
The 25-year-old center remained relatively healthy for most of the regular season, but left knee pain sidelined him down the stretch and continues to be a problem on the eve of the National Basketball Association playoffs. The NBA playoffs start tomorrow and the Sixers are set to take on the Brooklyn Nets.
Embiid is one of the game's dominant forces when healthy, averaging 27.5 points, 13.6 rebounds.

An ICC statement on Friday cited a lack of cooperation from all sides, leading to the rejection of the investigation. The White House also commented, calling the decision a "major global victory" for the rule of law.
Brand said he made those moves with the playoffs in mind.
Meanwhile, the 76ers acquired forward Tobias Harris from the Clippers in a deadline deal to pair with stars Embiid and Simmons.
Before jumping too far ahead since the playoffs are long and a whole new season, Philadelphia's main focus at the moment is making sure they find a way to win this upcoming series over Brooklyn since it's going to be far from easy. "I expect us to pass that".
Despite appearing to have a huge advantage over their rivals on paper, the Sixers realize the last thing they can do is underestimate the Nets, especially since the two teams split the four-game series during the regular season.
