As noted, Big Cass was backstage for last night’s RAW and word going around is that he is in the final stages of being cleared to return to the ring. PWInsider adds Cass was telling people that he has been cleared to return.
Cass has been out since August 2017 with a torn ACL. It was believed that he would be out until May but it looks like he will be back working the storylines before then.
