Tolliver, 35, will join the 11th team of his well-traveled career which began in 2007 after he went undrafted. The Missouri native last appeared with the Grizzlies during the bubble in Orlando last season.
He split the 2019-20 campaign between the Grizzlies, Kings and Blazers, appearing in 55 total games while averaging 3.6 PPG and 2.8 RPG. Tolliver is a career 37.3% shooter from beyond the arc.
While Tolliver will not be relied on to make a major impact, he will be expected to give Philadelphia some quality minutes off the bench.
