Former Strikeforce ISKA Lightweight Champion Clay Guida lost in his Shooto debut this past weekend, as he fell victim to an armbar from Yusuke Endo in the first round.

Guida was an injury replacement and took the fight on short notice against Endo, who was Shooto’s 2004 Rookie Champion in the 154-pound weight class. With the win, Endo improved his record within the Shooto organization to 5-1.

The fight was Guida’s first in Japan. In his previous two fights, Guida defeated UFC and Pride veteran Josh Thomson in March to win Strikeforce’s ISKA Lightweight Title, but Guida then lost the title in June to the undefeated Gilbert Melendez. While his overall MMA record is still an impressive 19-6, Guida has now lost three of his last four fights.

In the main event on the card, Akitoshi Hokazono won Shooto’s 132-pound title with a unanimous decision victory over Kenji Osawa. Also on the card, the six-fight winning streak of American Top Team member Cole Miller was snapped in his Japanese debut. The 145-pound Miller lost by unanimous decision to “Lion” Takeshi Inoue, who extended his own winning streak to four fights.
