McCallum was waived by the Spurs to make room for Andre Miller on February 29 after having played in 31 games. The third-year guard played in nine D-League contests this season as well, averaging 17.3 points and 4.8 assists.
From The Vertical:
Free-agent guard Ray McCallum is traveling Friday morning to Memphis and will likely sign a deal with the Grizzlies, league sources told The Vertical.
In the wake of guard Mario Chalmers’ season-ending injury and subsequent release, the Grizzlies are looking to bolster their guard depth, sources said.
Since his release from the San Antonio Spurs, McCallum has had discussions with the Houston Rockets and New York Knicks, sources said.
