The Fighters decided to go with money-only compensation for Ono as well.
[UPDATE 1/17 @ 3:57pm]
According to Tokyo Sports, the Fighters wanted Hitoki Iwase as compensation for losing Ono, but backed off after the veteran threatened to retire. The Dragons left Iwase off their list of protected players because they did not think the Fighters would pick him.
