According to F4WOnline, Drew McIntyre’s return to WWE is said to be more of a “creative issue” at this point.
McIntyre’s last appearance was at WrestleMania 39. Since then, he has been away dealing with a health issue/injury. He worked through the injury at WrestleMania, taking part in the Triple Threat Match where Gunther defeated both McIntyre and Sheamus to retain the Intercontinental title.
It was further noted that the “creative issue” is in regards to what WWE wants and what McIntyre wants, and when both sides agree to it.
McIntyre is in the last year of his current WWE contract.
