LAS VEGAS -- Trail Blazers guard Scoot Henderson and Rockets guard Amen Thompson put on impressive displays in their summer league debuts Friday, but left what ultimately became a 100-99 Houston win with injuries.

Henderson, the No. 3 overall pick by Portland, exited in the third quarter with a right shoulder injury and didn't return. Thompson left with a left ankle injury after taking an awkward fall when he attempted to block a shot under the basket in the fourth quarter. He, too, didn't come back.

"It's pretty sore," said Thompson, who added it was up to Houston's athletic training staff to determine whether he would return for more summer league action. "I just blocked the shot and landed on his foot, twisted my ankle."

He'll undergo an MRI on Saturday.

Henderson didn't speak to reporters after the game, though he walked through the media area without anything visible on his arm or shoulder.

Blazers summer league coach Jonah Herscu said he didn't have any updates on Henderson's injury.

"I haven't talked to the trainers yet," he said. "They were just being cautious with it."

Herscu later said he didn't see when the injury occurred.

Before they exited the game, Henderson and Thompson showed why Portland and Houston, respectively, selected them near the top of the lottery.

Both players showed impressive flashes throughout. Henderson, 19, finished with 15 points, 5 rebounds and 6 assists. Thompson, 20, had 16 points, 4 rebounds, 5 assists, 3 steals and 4 blocks in 28 minutes.

When Portland drafted Henderson, it was a clear sign of where things were headed with superstar guard Damian Lillard, who on July 1, officially requested a trade from the only team he has ever played for after seeing the Trail Blazers weren't adding veterans in free agency.

With Portland general manager Joe Cronin sitting courtside Friday night, the 6-foot-3 Henderson showed off the size, speed and strength that had him in a back-and-forth battle with Brandon Miller to be selected by the Charlotte Hornets with the second pick.

Henderson got into the lane at will, either setting up teammates for open 3s or getting to the rim for layups. He also hit a couple of pull-up jumpers early in the contest. And while his jumper was a little off as the game progressed, he found ways to be involved at both ends of the court, getting his hands on multiple balls defensively and continuing to push the pace.

That so much of his game at both ends of the court saw Henderson going head-to-head with Thompson only added to the intrigue.

"Scoot was great," Herscu said. "When he's in an attack mindset and getting in the paint, it's really good. And point guard is the first line of defense defensively, so I thought his pressure on Thompson was really good, picking him up near half court, in the back court. And so I thought he played with good thrust tonight."

Thompson, a playmaking 6-foot-7 guard, showed why he was the highest player drafted out of the Overtime Elite program -- one spot ahead of his twin brother, Ausar, who went fifth to Detroit.

Thompson showed an impressive feel for the game, repeatedly making the right play with the ball. He also made a couple of slick passes that drew cheers from the crowd. He looked completely at ease at both ends.

"We looked way better than we did in practice," Thompson said, "and just moving the ball. I just felt like we played a good game."

After Henderson and Thompson left the contest, there was still plenty of excitement down the stretch featuring multiple first-round picks on both sides over the past couple of drafts. Henderson's likely backcourt mate in Portland this season, Shaedon Sharpe -- the No. 7 pick last year -- had 21 points and 8 rebounds, but it was the No. 3 pick in last year's draft -- Houston's Jabari Smith Jr. -- who stole the show, finishing with 33 points and 7 rebounds, including the winning 3-pointer at the buzzer off a pass from Tari Eason.

"I don't know how Tari made that amazing kind of hook pass and led him," Rockets summer league coach Ben Sullivan said. "And then from my angle, Jabari caught it. I don't think he brought it down, and just let it go. Fortunately, it went in."
