Sources with knowledge of the meeting said that Stackhouse is scheduled to work out at the team's practice facility as the Knicks continue to search for proven players to fill out their roster.
The Knicks have recently auditioned point guards Jason Williams and Jamaal Tinsley while also negotiating with Milwaukee Bucks restricted free agent Ramon Sessions. It's believed that New York, except in Sessions' case, is generally searching for players it can acquire on one-year deals to preserve as much salary-cap space as possible for 2010 free agency.
Stackhouse would appear to have a decent shot at landing an offer from the Knicks, depending on the state of his game after a virtual year off, given that they have minutes available at shooting guard.
He became an unrestricted free agent last month after the Memphis Grizzlies bought out the final year of his contract for $2 million. Memphis acquired Stackhouse from the Dallas Mavericks in the four-team trade headlined by Shawn Marion and Orlando's Hedo Turkoglu.
Various injuries limited Stackhouse to just 10 games with the Mavericks last season. But he has a lifetime scoring average of 18.4 points per game and has made two trips to the All-Star Game in a 14-season career with four teams.
As for Williams, New York's exclusive negotiating rights with the point guard expire Thursday. But ESPN.com reported Tuesday that Williams and the Knicks could continue talks beyond that deadline -- even though Williams will become an unrestricted free agent Friday if he doesn't receive an offer from the Knicks that meets league guidelines.
"There's mutual intrigue," Knicks president Donnie Walsh told the New York Post after Williams' workout. "He looked good [and] seemed in good shape, but it's a process and could take time."
