Garlic Boy Ganaha no longer to Kawasaki's taste
The 28-year-old earlier this year won his appeal against a six-game suspension imposed for using intravenous drips in violation of the J-League's anti-doping rules.
Ganaha, who took the case to the Court of Arbitration for Sport, has slipped down the pecking order at Frontale, scoring just two league goals this season.
Ganaha's ban also cost him his place in the Japan national side. The striker scored three goals in six games after breaking into the team in 2006.
Kawasaki were also fined around $100,000 after club doctors put the player on the drip. While Ganaha did not take an illegal substance, intravenous treatment is banned under FIFA guidelines.
