That promo would've only made sense if they actually showed us who the mystery person was.
AEW has been having bad news all month and having Danielson come out and hype up 2 matches he's not gonna be involved in (but don't worry, he's "fine" and will be back...whatever that means) doesn't add much of anything to the PPV nor Blood & Guts. I think this kind of tease hurts both shows instead of helping them.
They should've just have Regal come out and basically do the same thing...and actually present the replacement wrestler.
at ZSJ just coming out and having a staredown with someone he's not gonna wrestle until who knows when
