Former Knicks point guard Mark Jackson will be reunited with Jeff Van Gundy and Patrick Ewing in Houston, The Post has learned.

Jackson, 38, will work out for the Rockets tomorrow and, if all goes well, debut Saturday against Minnesota.

The Rockets lack a true point guard and have been using Steve Francis in that role. Jackson, who ranks second behind John Stockton in career assists with 10,215, will likely serve as a backup.
