Portland Trail Blazers big man Zach Collins suffered a Grade 2 ankle sprain during a recent workout, according to Dwight Jaynes of NBC Sports Northwest.

Collins sustained the injury, which includes a torn ligament, while working out in his hometown of Las Vegas. Though he's been wearing a walking boot and walking with crutches ever since, the injury did not require surgery and is not considered especially serious. Collins is expected to be ready to play by the opening of training camp in September.

The No. 10 overall pick of the 2017 NBA Draft, Collins has flashed game-changing two-way talent over his first two years in the league, but has nevertheless been unable to make a sustained positive impact. The Gonzaga product averaged 6.6 points, 4.2 rebounds, and just less than one block in 17.9 minutes per game last season, shooting 47.3 percent from the field and 33.1 percent from beyond the arc – all substantial improvements compared to his NBA debut. Collins was especially effective in the postseason, helping Portland to a surprise Western Conference Finals appearance with borderline elite rim-protection and improved ability to finish through contact in the paint.

Still just 21, Collins is slated to start at power forward in 2019-20 after the offseason departure of Al-Farouq Aminu. Though ideally a center long-term, he has enough shooting potential and foot speed to play the 4, versatility that's especially key given Portland's absence of proven wings and glut of centers following the summer acquisitions of Hassan Whiteside and Pau Gasol. Incumbent starting center Jusuf Nurkic is set to return from a devastating leg injury after the All-Star break.

Collins is scheduled to be back at the Blazers' training facility next week.
