WEDNESDAY, 11:04am: The Raptors are hoping to sign Justin Dentmon by week's end, according to Marc Stein of ESPN.com (via Twitter). Scott Schroeder of Ridiculous Upside reports that the Raptors previously tried to call up Dentmon, but the University of Washington alum had already agreed to a 10-day deal with the Spurs (Twitter link).
As our 10-day tracker shows, Dentmon signed with the Spurs on March 24th, though the team terminated his contract early, according to RealGM's transactions log. Either way, Dentmon's 10-day deal would have expired by now, and it doesn't appear San Antonio is interested in bringing him back. The 26-year-old, who appeared in two games for the Spurs, has since rejoined the D-League's Austin Toros.
