Orlando Magic rookie Jalen Suggs will miss the rest of the NBA Summer League with a thumb injury.

The fifth overall pick in last month's draft, Suggs hurt his left thumb when he fell on a drive to the basket in Thursday's game against the Boston Celtics. 

The Magic said an MRI exam Friday confirmed the 20-year-old guard had sprained his left thumb. 

Suggs gained national acclaim as he led Gonzaga to the championship game of the NCAA Tournament in April, banking in a three-pointer at the buzzer to beat UCLA in the semi-finals. 

He impressed immediately in his first game in a Magic uniform, scoring 24 points and adding nine rebounds in just 28 minutes in his summer league debut against the Golden State Warriors on Monday.

Suggs averaged 15.3 points, 6.3 rebounds and 2.3 assists in three games in Las Vegas and will miss Orlando's final contest against the Houston Rockets on Saturday.
