strikeforcecrestStrikeforce lightweight champion Josh Thomson has been scratched from his title defense against Gilbert Melendez due to not being able to pass his medical screening for the event.

Thomson has been rehabilitating a broken leg suffered in training months ago, and apparently the injury has not been allowed the proper time to fully recover.

It was recently being reported by numerous sources that Mitsuhiro Ishida has been tabbed as a replacement for Thomson, and has since been able to confirm the news of the bout-change through Strikeforce.

They will face off at “Strikeforce: Carano vs. Cyborg“, which is slated for August 15 from the HP Pavilion in San Jose, California. The event will air live on Showtime.

The pair are far from strangers as Ishida holds the first defeat in the career of Melendez when they first met in Japan on New Years Eve, 2007. Ishida was able to control Melendez and edge out a hard fought unanimous decision in what was considered to be a mild upset at the time.

Melendez recently bounced back from losing his Strikeforce championship to Thomson in June of 2008 by knocking Rodrigo Damm senseless at “Strikeforce: Shamrock vs. Diaz” in April of this year.

Ishida will be looking to get back in the win column following a recent TKO defeat at the hands of Mizuto Hirota in Tokyo that came on the heels of back-to-back victories for the powerful wrestler known as “The Endless Warrior”.
