Brock Lesnar is back in the WWE Roster

Social media trend is about Brock Lesnar appearing on the WWE roster website.  Indeed, it is official that Lesnar's picture is posted.  However, there is no indication if Lesnar has any involvement for WrestleMania.  If so, he would be the main character to help Cody Rhodes finish his story.   

I do notice that Lesnar's picture is next to Bron Breakker.  Too early to even have a conversation or entertain a match.
