Morris is coming off two seasons with the Los Angeles Lakers. The veteran forward averaged 6.7 points and 4.4 rebounds per game in 2020-21. He spent time out of the rotation but then became a starter when Anthony Davis and LeBron James were out with injuries.
Morris started 22 straight games at one point and scored in double figures in 15 of those games.
He played a key role in helping L.A. win the 2020 championship in the Orlando, Florida, bubble, slotting in as the team's most-used big man aside from Davis in the NBA Finals.
Morris, however, played in only four games in the Lakers' 4-2 loss in the first round to the Phoenix Suns this year.
