As previously noted, an injury angle with Matt Riddle took place during the December 5th 2022 edition of WWE RAW which ended with Riddle being taken out of the arena on a stretcher.
According to Cassidy Haynes of BodySlam.net, sources told him that Riddle was suspended for a drug test failure during the summer and that’s why his match against Seth Rollins was postponed until Clash at the Castle. Haynes noted the following…
“I was able to confirm that the reason that WWE wrote Riddle of TV is because he has failed another drug test and will be sent to rehab. The belief going around is that he has already entered treatment, or will be going in soon as most programs run for 30 days and he would need to be finished in time for his return in six weeks.”
Haynes added that WWE no longer tests for marijuana and but didn’t note what exactly caused the failed test.
