There reportedly were big plans ahead for the "Lunatic Fringe" after WrestleMania.
Unfortunately, on the Christmas Day edition of Monday Night RAW, the "Lunatic Fringe" Dean Ambrose, suffered an elbow injury that required surgery and that ultimately would sideline the superstar. The following week on RAW, Michael Cole would confirm Ambrose's injury, stating that he would be out for approximately nine months. While it has not been determined whether that is an exaggerated date or not, it did put a halt on reported plans for the former WWE World Heavyweight Champion.
According to Dave Meltzer in the latest edition of the Wrestling Observer Newsletter, WWE had big plans in store for Dean Ambrose following WrestleMania 34. It has been rumored since April of 2017 that Roman Reigns would be taking on Brock Lesnar for the WWE Universal Championship at this year's WrestleMania. If Roman Reigns can win the Elimination Chamber match this Sunday, he will head to New Orleans and have that very match. Meltzer noted that plan was for Ambrose to turn on Roman Reigns and Seth Rollins and following WrestleMania, assuming Reigns goes on to challenge and defeat Brock Lesnar for the Universal Title, Ambrose would begin a program with his former shield brethren, and the two would feud over RAW's top championship.
This Sunday at the 'Elimination Chamber' PPV, Roman Reigns will have an opportunity to earn his way to that Universal Championship match against Brock Lesnar, but to do so, he must go through six other men inside of the structure known as the devil's playground; the Elimination Chamber.
