Josh Thomson (pictured) has suffered a foot injury and will be unable to compete on Sept. 10 against Maximo Blanco.
Sherdog.com learned of Thomson's injury on Tuesday from a source close to the contest. The promotion is seeking a replacement for the American Kickboxing Academy standout, but Strikeforce has yet to announce any news regarding the lightweight's injury.
Thomson was scheduled to meet Blanco at Strikeforce “Heavyweight Grand Prix Semifinals,” which will emanate from U.S. Bank Arena in Cincinnati. Featuring the final four competitors in Strikeforce's ongoing heavyweight tournament, the event will showcase Josh Barnett taking on Sergei Kharitonov and Daniel Cormier locking horns with Antonio Silva.
The show's main draw will air live on Showtime, while the preliminaries will be broadcast immediately prior on HDNet.
Thomson, 32, has split his last four bouts after stringing together eight-straight wins. After losing his Strikeforce lightweight championship to Gilbert Melendez in their 2009 rematch, “The Punk” rattled off consecutive victories over Pat Healy and Gesias Cavalcante in 2010.
Most recently, Thomson was defeated by Tatsuya Kawajiri on New Year's Eve, falling by unanimous decision at K-1 Dynamite 2010.
