The 23-year-old has yet to receive an official timetable for the injury that he suffered during their loss to the Milwaukee Bucks on Saturday night. He left that game eight minutes in to the first quarter, but the team did confirm that this was not related to the stiff back that kept him out of Thursday's game.
With Simmons out, it will be up to Joel Embiid to power their offense, along with Tobias Harris as support, and Embiid started to do just that on Monday night. Embiid went off for a career-high 49 points in a win over the Atlanta Hawks, which was the most by a Sixers player since Allen Iverson in 2005. They currently hold the fifth seed in the Eastern Conference, and have until April 15th to get in to the top four. They will have to work on that for now without Simmons, who has averaged 16.9 points, 7.9 rebounds, and 8.3 assists this season.
In another minor NBA injury note, the Memphis Grizzlies added to their injury list with Brandon Clarke being ruled out for two weeks with a quad injury. Clarke suffered the injury in their road loss to the Los Angeles Clippers on Monday night, as he left the game just three minutes in to the first quarter. He was originally ruled out with right hip soreness, but testing revealed the severity of the injury on Tuesday. He now joins Jaren Jackson Jr. on the injury list for the eighth-seeded Grizzlies, who have struggled during their current west coast trip. Clarke, the rookie out of Gonzaga, has posted 12.0 points and 5.8 rebounds per game on 62.3 percent shooting this season.
