The 28-year-old guard appeared in seven games during his 20 days with Cleveland. He averaged 6.1 points, 1.7 rebounds and 1.9 assists in 13.6 minutes per night and shot 46.2% from three-point range. Quinn, who also played 16 games for the Lakers earlier this season, is now a free agent and can sign with any team.
Players can only sign two 10-day contracts with the same team during a season, so the Cavs had to either give Cook a contract through the end of the season or let him go. They opted to keep the roster spot open for flexibility, sources tell Fedor.
The Cavs currently have 13 players, along with a pair of two-way contracts, and must fill at least one of the openings within two weeks.
