Matt Riddle was written off TV because "he has failed another drug test and will be sent to rehab."
Sources have told BodySlam.Net that the reason for pushing back the match was because Matt Riddle failed a drug test leading up to SummerSlam, this was also the last test under Vince McMahon’s regime. With Vince no longer in charge, a “new creative direction” was taken regarding Riddle, and his big match against Rollins was postponed until Clash at the Castle. Additionally, I was told that the company informed Riddle at the time that another failed drug test would result in a “rehab or fired” situation similar to what happened with Jeff Hardy previously.
This leads us to Matt Riddle’s most recent “six week” television write off. 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.
I asked for clarification on what exactly came up on the failed test, but it should be noted that WWE no longer tests for marijuana.
