At last night’s CES 48, Timothy Woods secured a leg lock on Tim Caron and tried to toss him to the mat. He succeeded in doing so, only the thing is, he misjudged the landing and speared himself onto the mat, neck first.
Woods was reportedly unconscious on the mat for a few minutes, per Sherdog, before he was stretchered off.
As the Bloody Elbow points out, this self own is reminiscent of that time back in 2007 when Gray Maynard did this to himself against Rob Emerson. However, that bout was ruled a no-contest, since Maynard injured Emerson’s ribs to the point that he couldn’t continue.
