#2 Lars Sullivan (Won't return until 2020)
Lars Sullivan’s main roster run isn’t something he would be proud of. First of all, he didn’t debut on Raw or SmackDown Live until after WrestleMania because he was suffering from mental illness which included anxiety attacks. He finally made his appearance on Raw when Kurt Angle was addressing the crowd after his loss to Baron Corbin at WrestleMania 35.
The Freak didn’t care that Angle was retired and he still laid hands on him. Later, WWE involved him in a feud with The Lucha House Party and now, he is suffering from a knee injury. Reports had earlier suggested that the injury is worse than first expected but latest reports tell a different story.
“Lars Sullivan was listed on WWE’s internal injury report as being out until late June 2020. Considering his experience with knee surgery in the past, he is not actually expected to be out that long.”
While things may turn out to be better than originally expected for Sullivan, he still isn't likely to be seen near a WWE ring until next year.
