Ryan said he has had a good deal of help along the way during the past four months, citing his wife, Danielle, as one of his primary supporters.
"Away from the rink, my wife has been absolute rock star allowing me to do this," he said. "She's taken on more than she's probably had to, but she's been absolutely incredible."
He said he has also leaned on several players who have had the same issues.
"Everybody knows some of the guys who've been through the program and can be a little more vocal about it, and I've talked to all of those guys," Ryan said. "I've played with some of them and really leaned on them. Some guys reached out that I had no clue that had already gone through it, and they did it quietly and they did it in June, and it worked for them. … That kind of support within the NHL I found overwhelming. It was incredible how many guys reached out that I had no prior contact with, but it was incredible."
The 32-year-old is in the fifth season of a seven-year, $50.75 million contract with an average annual value of $7.25 million but has not scored more than 20 goals or 50 points since 2015-16. He had four straight seasons with at least 31 goals from 2008-12 with the Anaheim Ducks, who traded him to Ottawa on July 5, 2013.
"People have reservations about where I am in my career and contract and I understand that," he said. "I'm not saying I am going to come out of this and play like the $7 million guy that I want to be as much as everybody else does, but this is a chance for me to reset and prove that I still have some years left in this League."
