Lars Sullivan who is currently out in the injured list is reportedly not recovering as expexted, according to Fightful select.

The report notes that Sullivan's progress is "slow" ...

"We’re told that his knee injury recovery is progressing slowly, even slower than some he’s experienced in the past."

Sullivan had been pushed as Vince McMahon's next big freak project, but a series of personal problems with anxiety halted his initial debut and it wasn't long before he sustained an injury that required surgery.

Sullivan is not expected to return before Summer 2020 unless his recovery significantly improves.
