It's been a couple of months now since fans last saw Roman Reigns in the WWE, and fans will likely have to wait a few more until they see him back in the ring again.

The Big Dog hasn't been seen in the WWE since he announced on Monday Night Raw in October that he had been diagnosed with leukaemia and that he would be taking time away from the business to receive treatment.

The last image to date that fans have of him in the WWE is when he united with his Shield brothers in Dean Ambrose and Seth Rollins to perform their iconic fist bump salute on the stage following his announcement.

During an interview with WSVN-TV Entertainment Reporter Chris Van Vliet, via Wrestling Inc, Chris Jericho revealed that he has been in communication with Reigns throughout his leukaemia treatment.

Y2J stated that while he doesn't know a lot about leukaemia, he's heard that things are going well for Roman, and that he believes it's just a matter of time before he makes a return.

He said: "He's doing his treatment, and I think things are going really well. I don't really know much about leukemia. I don't know what the endgame is as far as when you're 'cured' -- when it goes into remission, when you can do physical matches or travel or whatever it is. But we talk to him quite a bit.

"I've got a group text with him in it, and I text him on the side quite a bit. He always seems to be doing pretty well and in good spirits... We love him, and I think it's just a matter of time before he comes back. But more importantly -- that he stays healthy for his family, for sure."

While it is unclear as to when The Big Dog will be back performing in the WWE, many will be hoping it's soon.

However, as Jericho says himself, it's important that he puts his health first before the fans and before he decides to make a return to wrestle in the ring. Fingers crossed he returns at some point before the end of the year.

As for Jericho himself, big things are in store for him this year, but away from the WWE. He recently signed a three-year deal with the newly-formed and highly-anticipated All Elite Wrestling and was revealed by the promotion earlier this week.
