Houston Rockets rookie Jalen Green will likely miss the rest of the Summer League with right hamstring pain, according to Chris Haynes of Yahoo Sports.

The No. 2 pick in last month’s draft left Thursday’s 92-76 loss to the Toronto Raptors in the first half and did not return. Green had been one of the stars of the Summer League, averaging 20.3 points on 51.4% shooting, 4.3 rebounds and two assists in three games.

Rockets don’t think injury is a “major concern”, say ESPN. However, he should undergo a precautionary MRI.

Green, who chose not to go the college route, played in the NBA G League last year, averaging 17.9 points, 4.1 rebounds and 2.8 assists per game while shooting 46 , 1% of the terrain and 36.5% of the depths.
