Roman Reigns and his battle with leukemia continues, and we're going to have an update soon.

Vince McMahon on Twitter announced that the former WWE Universal Champion would appear on WWE Raw to address his leukemia. However, it wasn't mentioned whether or not the appearance would be live or taped.

There was a source that reached out to Fightful Wrestling on Thursday and said that they expect the presence of all three members of the Shield at WWE Fastlane -- but didn't clarify the significance of that statement or any plans, which was covered on the Fightful Select Q&A Podcast. I should note we've not yet confirmed this with a second source.

Reigns was forced away from the ring last year when he announced that leukemia that he'd battled over a decade before had returned. As a result, he relinquished his recently won WWE Universal Championship, which was later won by current champion Brock Lesnar. Reigns' fellow Shield member Seth Rollins is slated to face Brock Lesnar at WrestleMania in April.

Fightful Wrestling will have an update on the situation as soon as we get it, as well as full, live coverage of next week's WWE Raw.
