To Craig Patrick, it was "personal issues"
"No, I'm not going to talk about our discussion," Patrick said, saying Palffy cited only "personal reasons." Palffy told Patrick of his decision Tuesday morning. They agreed not to announce it until Wednesday because Patrick hoped Palffy would reconsider.
To the Slovak paper, it was a shoulder injury
The shoulder injury led to his decision to retire, he told the Sport daily, a Slovak newspaper.
"I have talked to my doctor and he did not recommend a third operation," Palffy told the newspaper.
Here's part of an article that mentions that he retired because of his arm, and then mentions that he may consider a comeback.http://www.sme.sk/c/2628595/palffy-sa-mozno-vrati.html
Even going back to an old Netwolf post, there was a pregame interview where EJ admitted that "Palffy quit"
On pregame, Stan was talking to EJ and asked him if he was surprised at how things went. EJ said yes, and listed all the players that they missed out on for the full season: "Mario retired, Thibault got hurt, Palffy quit."
Further confirmation that Palffy wasn't hurt or me reading too much into how things are worded? You decide.
