Nets small forward Rondae Hollis-Jefferson suffered a left adductor strain on Saturday during Jeremy Lin's exhibition game in China, the team announced.
Hollis-Jefferson, who will begin rehab immediately, was participating in the 2018 Jeremy Lin All-Star game alongside teammate Spencer Dinwiddie when he injured himself on a dunk attempt, according to Nets Daily.
The recovery time for Hollis-Jefferson's injury was not immediately clear. The 23-year-old averaged 13.9 points, 2.5 assists, and 6.8 rebounds per game in 68 games for the Nets last season.
Through three NBA seasons, all with the Nets, Hollis-Jefferson has played in 175 games, including a career-high 78 games in 2016-17.
The Nets will begin their preseason slate on Oct. 3 when they take on the Knicks at Barclays Center.
