Phoenix took time off over the summer for a death in the family.
WWE sources indicated they weren't surprised to see that Phoenix had given notice as she seemed to be "going through the motions" over the last year.
Phoenix was signed to the company in 2005 and debuted in 2006 on the Raw brand. Phoenix was on the shelf for some time after fracturing her jaw on live TV, but returned over the summer of 2007. She quickly moved into the top slot as one of the best in-ring performers on the Divas side of the company. She held both the WWE Women's and WWE Divas title and was the second women to work the Royal Rumble bout.
Should she decide to work outside of WWE, Phoenix would retain ownership of her ring name, as she used it prior to her WWE run.
