Flowers agreed to a two-way contract with the Clippers on Thursday, Keith Smith of Spotrac.com reports.
Flowers initially committed to play collegiately at Louisville but ultimately chose to play in the NBL in Australia with the Adelaide 36ers last year. He averaged 5.5 points and 3.1 rebounds in 14.4 minutes per game with Adelaide and will now attempt to carve out a role in the NBA.
