The Hawks announced Wednesday that Bembry underwent an MRI last week. There was no indication how the injury happened, but he has been working out at team facilities through much of the offseason.
Bembry will be held out of all basketball activities for four to six weeks. He will definitely miss training camp this month and likely all five preseason games.
If forced to sit out for the full six weeks, Bembry would miss several regular-season games. The Hawks open Oct. 18 against the Dallas Mavericks.
A first-round pick in 2016, the 6-foot-6 Bembry played sparingly for Atlanta in his rookie season, averaging 2.7 points and 9.8 minutes in 38 games.
His playing time figures to increase this season, with the Hawks beginning a long-range rebuilding plan.
