WWE recently reached out to UFC lightweight champion Conor McGregor about an appearance at Wrestlemania 33, according to a new report by The UK Sun.
"WWE has made no secret of its desire to do something with Conor McGregor and there were talks between the two parties about this year," a source told The Sun. "Because he's taking time off from the UFC, there was a talk about doing something at this year's Wrestlemania in April, but it wasn't to be despite a hefty offer."
McGregor himself has confirmed WWE's interest in his services, something Triple H is on record as to talking about. The Notorious One made headlines last August when he called out the entire WWE locker room and then apologized to absolutely no one.
WWE utilized Ronda Rousey in a surprise appearance with The Rock at Wrestlemania 31 a couple years ago but was unable to followup on it.
