WWE released the following statement:
WWE has come to terms on the release of WWE Superstar Austin Aries. WWE wishes Aries the best in all of his future endeavors.
Austin Aries is a former ROH World Champion and made an appearance before going to WWE back in July of 2015, replacing Roderick Strong who also went to WWE. It is some interesting timing as Aries still has a lot of good will with wrestling fans and ROH is in an interesting position while under SBG who could potentially become the largest TV media company in the US. Couple that with the relationship between NJPW and ROH and Aries could definitely make some waves.
The Wrestling Observer is reporting Aries asked for his release.
Aries posted these two tweets today
It's a beautiful day.
