Segments changed on Raw due to lack of medical clearance.
According to Dave Meltzer on the latest episode of Wrestling Observer Radio, Ricochet and various WWE legends were not medically cleared for last night's WWE Raw Reunion.
Meltzer reports that Ricochet is dealing with an elbow infection. He was reportedly supposed to be in Seth Rollins' spot, working against AJ Styles and The OC before being saved by D-Generation X and the New World Order. Rollins ended up getting the moment with the legendary groups.
Meltzer goes on to report that Rikishi and Pat Patterson were not medically cleared either. Rikishi was reportedly set to do a Stink Face to D-Von Dudley. Instead, he remained at ringside while The Usos battled The Revival. Patterson won the WWE 24/7 Title by pinning Drake Maverick with his foot but lost the title shortly after to Gerald Brisco. Patterson was never shown taking a bump or being pinned in the segment as WWE had to work around his lack of medical clearance.
Finally, fans may have noticed that Sid was absent from the show despite being advertised. Meltzer reports that Sid told WWE in advance that he would not be present.
