During last night’s episode of the Wrestling Observer Radio, Dave Meltzer was doing Q&A when a question about former WWE World Heavyweight Champion Christian was brought up. The question was about a possible retirement match for Christian.
Meltzer said that WWE could do a retirement match for Christian if they wanted to. The last couple of years the promotion stopped using him as he was getting too many concussions and that’s why they stopped using him.
There’s nothing stopping Christian from not wrestling again, but because of the concussions, WWE didn’t feel like investing any more time into the character.
