Kingson, who has previously played in the Premier League for Birmingham, Wigan and Blackpool, has failed to find a new club since being released from Bloomfield Road last year with his career suffering an alarming slump.
According to his wife, Adelaide Tawiah, she not only made him lose his form, but also rendered him impotent with the use of black magic.
"I messed up Richard’s life ever since we got married. I used my evil powers to trouble his career, I’ve been working on him spiritually to the point he could not perform in bed," she said on a Nigerian TV show.
The show she appeared on was one hosted by a preacher called TB Joshua, who had been attempting to cast out the ‘evil spirit’ that supposedly lived inside of her.
Kingson, who is Ghana’s most capped player, has now taken to Facebook to defend his wife.
"My wife is not a witch," he said in the Facebook post.
Tawiah has also rejected claims that she is a witch, explaining it was the spirit that was being cast out of her that spoke.
She later declared: "I can’t even remember what took place [when making the comments]."
