The Grizzlies traded Tillman (knee) to the Celtics in exchange for Lamar Stevens and two future second-round draft picks Wednesday, Adrian Wojnarowski of ESPN reports.
Tillman is currently dealing with a left knee injury, but he's not expected to be sidelined for a lengthy period. The 24-year-old big man was averaging 6.0 points, 4.6 rebounds, 1.7 assists, 1.2 steals and 1.0 blocks in 20.6 minutes across 34 appearances in 2023-24 for Memphis. With the Celtics, Tillman will likely serve as frontcourt depth alongside Al Horford and Luke Kornet behind Kristaps Porzingis. While the deal became official Wednesday night, Tillman presumably won't be able to debut versus the Hawks, so his next chance to suit up will come Friday versus Washington.
