Tyson Chandler and Mike Bibby practiced for the first time yesterday with the Knicks, but interim general manager Glen Grunwald’s work wasn’t done.

He was holed up in his Westchester office, working like a machine, chasing ex-Knick Jamal Crawford and Mavericks’ unheralded point guard J.J. Barea, according to NBA sources.

Crawford’s agent, Andy Miller, has been trying desperately for the past 48 hours to broker a three-team sign-and-trade deal between the Knicks, Hawks and another club under the salary cap to find a creative way to pay Crawford his market value, sources told The Post. The Warriors are one team Miller has tried to engage.
