Tillie, undrafted out of Gonzaga in 2020, has played a more prominent role for the Grizzlies lately with several teammates in the league's health and safety protocols. Tillie had been on a two-way contract, which the Grizzlies converted into a regular NBA deal -- including for the 2022-23 season.
Memphis waived guard Sam Merrill, who sources say will undergo a procedure on his left ankle and be sidelined for three to four months. Merrill had a guaranteed contract for the rest of this season and had made a positive impression with Memphis.
Tillie, 23, is a native of France and has averaged over 20 minutes in Memphis' past four games, which included posting 4 rebounds, 3 assists, 2 blocks and 2 steals in Friday's victory over the San Antonio Spurs.
