Jackson signed a non-guaranteed contract with Phoenix last month. He appeared in two preseason games.
Jackson, 24, has five years of NBA experience, though he missed his entire rookie season due to a foot injury. He was an early second-round pick in 2017 and spent his first three NBA seasons with the Pelicans. He played the last two seasons with the Pistons.
Jackson averaged 9.8 PPG in 40 games during his first season in Detroit and made 40.7% of his 3-point tries. He averaged a career-best 10.6 PPG in 53 games last season but his 3-point shooting cratered to 30.8%.
Jackson became a free agent in late June when Detroit declined its $3.15MM option on his contract. He’ll return to the open market later this week, assuming he clears waivers.
