When Strikeforce announced earlier today that Derek Brunson had been pulled from a bout with Ronaldo Souza at the organization’s upcoming show on March 3 due to a failed medical it seemed like another instance of bad luck for an already embattled promotion. However, as it turns out Brunson’s situation did not stem from an injury or substance issue but rather an Ohio Athletic Commission’s policy about contact lenses.

Wrote Brunson on his Twitter account, “Ok here’s the deal … I’ve been fighting with contacts for eleven fights (and it) never was an issue. Ohio won’t pass my eye exam.”

“And by the way, I’m bummed,” the 28-year old continued. “I had a month to prepare for the Jacare fight. Was working a lot of stand-up and takedown defense. Was certain to TKO or KO (him).”

Brunson is 9-0 as a professional with seven stoppages. His last outing came in November where he won a Unanimous Decision over Nate James, his third victory as a Strikeforce middleweight.

Strikeforce has said it is seeking a replacement for Brunson though it remains unclear whether or not they’ll be able to find one given the short amount of time involved.
