Celtics forward Lamar Stevens was among four players on non-guaranteed Exhibit 9 training camp contracts to make an opening night roster, as relayed by Luke Adams of Hoops Rumors.

Nets center Harry Giles, Knicks point guard Ryan Arcidiacono and Hornets guard Edmond Sumner are the others.

Stevens, 26, is in his first season with Boston and three years with the Cavaliers. He appeared in 62 games last season, averaging 5.3 points and 3.3 rebounds.

Exhibit 9 contracts are usually given to players for training camp and who aren’t expected to make the team. But they come with partial guarantees if the player does make the cut — and generally small raises if the player is still with the club a month or so into the season. 

Sumner, 27, appeared in 53 games with the Nets last season, while Arcidiacono, 29, has played with the Knicks on a couple of occasions, and has spent time with the Bulls and Trail Blazers as well.

Giles, 25, last played in the NBA with Portland in 2020-21. He spent two years before that with the Kings.
