"I believe that this team, that this city, is going to win a championship, and I'm going to be the biggest fan."

Bittersweet news out of Music City this week: Nashville Predators captain, Mike Fisher, is retiring from the NHL. In a heartfelt letter to fans published in The Tennessean, Fisher announced that he was hanging up his skates for good.

"This is the hardest decision I've ever had to make, but I know I've made the right one. I've decided to retire from the NHL. I kept praying for peace about the next step in my life. A peace that said this is God's will for your future. A peace that said whether or not this was the right time to walk away," he wrote. "I don't believe it came in a single instance or some aha moment, but as time passed, I gradually became certain that it was right for me to retire. I believe God gave me the ability to play hockey, and I was helped by dozens of individuals along the way, so it's not just up to me on when it's time to say goodbye."

The hockey star, who has been married to country music songstress Carrie Underwood since 2010, added that the Predator's recent Stanley Cup run only made his decision harder.

"Knowing we were so close to winning it all in June only makes it more difficult to leave it behind, but I do so with hope," he added. "Endings are always tough, but I believe when something ends, there are new beginnings, new opportunities and new things to be excited for, too."

Though they didn't manage to pull it off this year, Fisher is confident that Nashville will take home the cup someday. "I believe that this team, that this city, is going to win a championship, and I'm going to be the biggest fan," he continued. "No one will be happier than I will be to see it happen, because, these fans, they deserve it."

Fisher, who originally hails from Canada, tallied 276 goals and 309 assists over the course of 1,088 NHL games with the Predators and Ottawa Senators, according to ESPN. Fisher and Underwood have one two-year-old son named Isaiah.

We wish him luck in his future endeavors, although he'll always be number 12 to us.
