'Wheel of Fortune' Wrestler Defends Pat Sajak After He Gets Hate for Headlock

Pat Sajak was simply being funny when he showed off his wrestling skills on a contestant ... so says the guy who took it on the chin, and now he's urging folks to cut the "Wheel of Fortune" host some slack.

We spoke to Fred Jackson who tells us ... as a pro wrestler and a showbiz guy, he absolutely loved the moment, and it was actually one of the highlights of the whole show! He says he's the only one who has any business being upset about it, but he's perfectly OK with it.

ICYMI, the 'Wheel' host came under fire after Tuesday's episode, where Fred revealed he's a pro wrestler ... and after he won the bonus round, PS ran over and applied a wrestling move called the "chicken wing."

Fred found it super funny and all done in jest, adding he understands if it isn't everyone's sense of humor -- but he says all the backlash against Pat is taking it too far.

BTW, Fred says the moment was absolutely not staged -- Pat had a really firm grip on him, and he claims he couldn't get loose if he tried.

No injuries, though, so ... no blood, no foul. Standard 'Wheel' rules.
