On the heels of its first full season, the Professional Fighters League appears to have a new heavyweight for its second year.

Japanese veteran Satoshi Ishii (18-8-1), a judo standout based in California, recently said on Twitter he has signed with the PFL, presumably to be a part of the second heavyweight regular season later this year.

Dear supporters and fans,

I just signed with PFL. Match coming soon.

I really appreciate everyday support from my Balkan, Slavic and worldwide fans!

I’ll inform you about my fighting schedule as soon as I can. Love, Satoshi! pic.twitter.com/2YzMsO02ni — Satoshi Ishii | 石井 慧 (@SatoshiIshii) December 30, 2018

Monday night, the PFL wrapped up its first season by crowning six inaugural champions – each of whom won $1 million. At heavyweight, Philipe Lins beat Josh Copeland with a TKO to take the top prize.

PFL fighters had two regular-season bouts to earn points to qualify for an eight-man playoff bracket. In the playoffs, to reach the finals, fighters had to win two fights in a single night.

Ishii has won three straight fights, all by first-round submission. Those wins came after a rough stretch that saw him drop four of five fights, including two bouts under the Bellator banner.

At Bellator 157 in 2016, Ishii dropped a split decision to Quinton “Rampage” Jackson. And at Bellator 169, he dropped a unanimous decision to Muhammad “King Mo” Lawal during a three-fight skid.

Ishii’s resume includes fights against Fedor Emelianenko and Mirko Cro Cop, as well as wins over former UFC heavyweight champion Tim Sylvia and three-time UFC title challenger Pedro Rizzo and victories over UFC vets Jeff Monson, Phil De Fries, Heath Herring and Sean McCorkle.
