The Trail Blazers have signed Keylan Boone, Samson Johnson and Mark Armstrong to Exhibit 10 contracts, Joe Freeman of The Oregonian tweets.

After going undrafted in 2025, Boone spent most of last season with the Zerofees Southland Sharks of the NBL. He also had a brief stay in the NBA G League with the South Bay Lakers. Boone, a forward, played five seasons of college ball — three with Oklahoma State and one apiece with Pacific and UNLV.

The 6’10” Johnson played four years for UConn, winning two national championships in 2023 and 2024. Johnson went undrafted in 2o25 and spent last season in the G League with the Noblesville Boom, the Pacers’ affiliate. He averaged 9.2 points and 4.2 rebounds in 21 minutes per game.

The Rip City Remix, Portland’s affiliate, recently acquired the returning player rights to Armstrong. He went undrafted out of Villanova in 2024. The 6’2” guard has appeared in 80 G League games over the past two seasons, including 49 with the Texas Legends last season. He averaged 11.9 points and 2.8 assists in 20.5 minutes per contest with the Legends.

That trio is ticketed for the Remix, according to Freeman. They’ll receive bonuses up to $91K if they stay with the Remix for at least 60 days.
