Rey Mysterio recently spoke with The Record Newspaper in Mexico and commented on his WWE suspension. During the interview Mysterio said that he failed the test because of a drug he’s taking for his knee and arm, and furthered his comments by saying that he had a prescription for the medication. However, because he had to fly to The UK for SummerSlam promotion, and because he was on vacation for a small period of time, he was unable to show WWE the valid prescription by the deadline they gave him and was suspended as a result.
