Next week, the players currently under contract and those trying to earn an NBA tryout will meet at the Trail Blazers' practice facility in Tualatin to begin preparations for the Las Vegas Summer League. Current Trail Blazers such as Zach Collins, Caleb Swanigan, Jake Layman, Wade Baldwin IV and Georgios Papagiannis have been working out at the practice facility for at least the last month, though official summer league practices start early next week as the team gets ready for their first contest of the summer exhibition on July 7 versus the Utah Jazz.

While the team has yet to release their summer league roster, reports from media and the players themselves indicate the it is well on the way to being finalized. So here's who we know as of this point plans on suiting up for the Trail Blazers in Las Vegas, though it should be noted that there are any number of reasons, from better opportunities to injuries, that the names could change up to, and even after, the official roster is announced.

• For starters, all of the aforementioned players currently under contract (Collins, Swanigan, Layman, Baldwin IV and Papagiannis) are expected to play at summer league. The one caveat is Layman, who will have to his has contract for next season picked up by June 30 lest he become an unrestricted free agent. It is still possible Layman plays for the Trail Blazers at summer league even if the team doesn't pick up his option.

• Then there's the rookies the Trail Blazers draft/acquired during the 2018 Draft. One assumes Anfernee Simons, who the Trail Blazers selected with the 24th overall pick, is going to play with the team in Las Vegas, though it wasn't specifically addressed during his introduction on Monday. The same goes for Gary Trent Jr., who the Trail Blazers acquired from the Sacramento Kings, though as a second round pick, his contract has to be negotiated. Even if Trent Jr. hasn't been signed to his NBA contract for next season, it's still possible, and even likely, that he'll play at summer league.
