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.

The Grizzlies will soon sign guard Briante Weber of the NBA Developement League's Sioux Falls SkyForce to a 10-day contract, sources said. Memphis is also without starting point guard Mike Conley, who has a foot injury.

Since his release from the San Antonio Spurs, McCallum has had discussions with the Houston Rockets and New York Knicks, sources said.

McCallum appeared in 31 games for the Spurs this season, averaging 2.2 points and 1.1 assists. He was waived on Feb. 29 to create room for the signing of Andre Miller.

McCallum was the 36th pick of the 2013 NBA draft by Sacramento. He played two years with the Kings before an offseason trade to the Spurs.
