Cook, 25, was a first round selection of the Philadelphia 76ers in the 2007 NBA Draft, but made his debut with the Miami Heat. After three seasons with the team, including some time with the D-League's Iowa Energy, he was traded to the Oklahoma City Thunder in 2010. He was eventually traded to the Rockets in 2012 as part of the deal that sent James Harden from the Thunder as well.
In six seasons, Cook has played in 295 regular season games, starting in 49, and has also seen time in 40 playoff games. He has a career average of 6.9 points per game with 0.8 assists and 2.2 rebounds.
Cook cleared waivers on Friday due to the $3.1 million contract that would have been absorbed by the claiming team, according to Stein.
