Federal authorities reportedly are investigating threats made by Islamic sympathizers against former Special Forces soldier and current UFC fighter Tim Kennedy.

The Army Times reported Wednesday that followers of ISIS have made “recent credible threats” against Kennedy. But that doesn’t mean Kennedy is shying away from the fight.

“Just spoke to the FBI regarding some recent credible threats towards me by #ISIS,” Kennedy wrote in a Facebook post Wednesday. “They were not overly thrilled with my response…’Let those cowards come.’”

Kennedy served in the 7th Special Forces Group and is now a sergeant first class with the Texas National Guard, according to The Army Times. Kennedy told the paper he usually gets up to 10 threats per day over social media. He said most of the threats are from “military trolls” who target military figures.

“They said, ‘Are you aware of this stuff?’ I said, ‘Yes.’ They said, ‘We think this is somewhat credible,’” Kennedy told The Army Times. “Then I said, ‘I’m kind of desensitized to this stuff, so maybe you should tell me what my level of alarm should be.’

Kennedy, who teaches others to defend themselves in certain dangerous situations through his group Sheepdog Response, told the paper he doesn’t let the threats bother him.

“I teach people how to live with threats like this. Who would I be to be cowering to a bunch of gutless cowards acting like a bunch of tough guys online?” he added.

Kennedy is currently ranked No. 6 in the UFC’s middleweight division.
