Additionally, the WWE released a statement:

Tonight on Monday Night Raw, Roman Reigns (aka Joe Anoa’i) announced that he is relinquishing the WWE Universal Championship and taking a leave of absence from WWE as he once again fights leukemia, which had been in remission since late 2008. Reigns is taking his battle with leukemia public in an effort to raise awareness and funds for research in order to advance cures for the disease.

People soon took to Twitter with the hashtag #ThankYouRoman to show their support.
