LAS VEGAS (AP) — Scoot Henderson of the Portland Trail Blazers and Amen Thompson of the Houston Rockets, both top-four picks in the NBA draft, left their NBA 2K24 Summer League matchup early Friday with injuries.

Thompson reportedly is expected to be shut down for the remainder of Summer League after an MRI revealed a Grade 2 sprain on the Houston rookie’s left ankle. The No. 4 pick landed awkwardly when he attempted to block a shot in the fourth quarter of the Rockets’ 100-99 victory over the Blazers.

An MRI revealed Rockets rookie guard Amen Thompson has a Grade 2 ankle sprain and will be out 2-3 weeks, a source told @andscape @espn. Thompson will be in a boot for a week and is expected to miss the rest of summer league after suffering the injury against Portland yesterday.

Henderson injured his right shoulder in the same game, but was not made available to the media. He didn’t appear concerned in the arena afterward.

Henderson, the No. 3 pick in the draft out of the G League Ignite, didn’t have his shoulder in a brace or sling. He had 15 points, six assists and five rebounds in 21 minutes, scoring 13 points in the first quarter. He left in the third quarter.

Thompson, the No. 4 pick out of Overtime Elite, had 16 points, five assists and four rebounds in 28 minutes.

Both teams next play Sunday. The Blazers face the San Antonio Spurs and No. 1 selection Victor Wembanyama, and Houston plays the Detroit Pistons, who drafted Ausar Thompson, Amen’s twin brother, with the No. 5 pick.
