#2 Lars Sullivan
Lars Sullivan has also been out for a long time, injuring himself back in June 2019. He was set to be out for 6-9 months, and he could be on the road to recovery, but his issues off-screen could keep him out for a prolonged period.
It is still uncertain as to if he even has a WWE career, but one thing that is certain is that he won't be at Super ShowDown. Coincidentally, his penultimate match in WWE before his injury was at last year's Super ShowDown, where he faced the Lucha House Party in a handicap match and won.
#1 Aleister Black
Aleister Black is yet another Superstar who will not be at Super ShowDown because of political reasons.
Dave Meltzer of Wrestling Observer Newsletter revealed that Black was mostly likely pulled out of the past Saudi Arabia shows because of his tattoos and the religious symbolism behind it.
“This was not his choice. This was a choice made for him. I don’t know if it was made by the Saudi Arabian government or it was made by WWE because they didn’t want to offend the Saudi Arabian government. The deal with him is that his tattoos apparently have some religious connotations that the belief is will offend the host of the show so they don’t want him going. That’s the Aleister Black story.”
