Janet Jackson just can't catch a break on her North American All for You tour. Following a spate of postponements due to health and other issues, Jackson's show Tuesday (Aug. 21) in New York is being moved up a day to accommodate a WNBA playoff game.

"Due to the New York Liberty's WNBA playoffs, Janet Jackson's concert at Madison Square Garden originally scheduled for Tuesday, August 21st, has been rescheduled to Monday, August 20th," reads a statement on the venue's official Web site. "All tickets purchased for the August 21st show will be valid for the August 20th show." Jackson's Aug. 22 and 23 shows at the venue are not affected.

The Liberty will play the Miami Sol in game one of the Eastern Conference Semifinals on Sunday (Aug. 19). Game two has been slated in for Tuesday.

This makes the sixth date on Jackson's tour to not go off as originally scheduled. Last week, a nasty flu contracted by the artist forced the postponement of shows in Cleveland, Indianapolis, and Pittsburgh. Additionally, a show in Milwaukee was scotched when Jackson needed emergency dental surgery. The North American tour's kick off in Vancouver was postponed because an integral piece of the stage set didn't arrive in time for rehearsals and the planned premiere show.
