The Grizzlies signed Harrison on Thursday.
Harrison will join his seventh team in as many seasons in 2023-24. Last year, he made five appearances for the Trail Blazers and averaged 8.8 points, 6.0 assists, 4.4 rebounds and 2.2 steals in 24.0 minutes. Harrison will likely compete for a depth role in Memphis' backcourt and is unlikely to see significant playing time.
