It's back to the drawing board for the Japan Basketball Association.

The JBA's board members held a meeting Wednesday and rejected a proposal to merge the bj-league, JBL and JBL2 teams into a new 36-team professional hoop circuit for the 2013 season.

The latest proposal was unilaterally concocted behind closed doors without the bj-league's knowledge, input or support, The Japan Times has learned after speaking to bj-league officials.
