Houston Rockets rookie Jalen Green will likely be held out of the rest of Summer League as a precaution due to right hamstring soreness, according to Chris Haynes of Yahoo Sports.

Green was limping in Thursday’s Summer League game and got stretched out on the sideline, but ultimately never returned.

The Rockets do not believe the No. 2 pick’s injury is a “significant concern,” but he will undergo an MRI as a precaution, Tim MacMahon of ESPN tweets.

In three Summer League games, the 19-year-old averaged 20.3 points, 4.3 rebounds and 2.0 assists per game.

NBA training camp begins on Sept. 28, so Green will have over a month to rest and recover to make sure he’s 100 percent for the start of the regular season that tips off on Oct. 19.
