Vladimir Tarasenko will take the faceoff in what promises to be an emotional moment for everyone in the building.

ST. LOUIS - Members of Ari Dougan's family - her mom, Lori, dad, Shawn, and brothers Aiden and Liam - will drop the ceremonial puck before the Hockey Fights Cancer game on Dec 1 vs. Los Angeles.

Fans in attendance are encouraged to use their cell phone's flashlight feature during the puck drop to help #SpreadArisLight ahead of the game.

Ari, who joined Tarasenko and the Blues on a road trip last March and captured the hearts of thousands of Blues fans who followed her story, passed away on Nov. 11 after an eight-year battle with cancer.

Kids Rock Cancer - an organization created at Maryville University to help children cope with the challenges of a cancer diagnosis through music - will sing "All Together Now" prior to Dec. 1 game. Ari was a participant in the Kids Rock Cancer program before her passing.

In addition, five youth hockey players who have battled cancer will join Blues players on the ice during the national anthem, which will be performed by Eva Millar-Galvan, a cancer survivor and officer for the St. Louis Metropolitan Police Department. Before the game, players will wear special Hockey Fights Cancer jerseys in warm-ups, which will be auctioned to raise money for organizations that fund cancer research.

Fans can help raise money to fight cancer by purchasing autographed mystery pucks or special edition lapel pins outside Section 114 at the game. Fans can also download an "I Fight For" sign at stlouisblues.com/HFC to display on their social media accounts.

Tickets for the Hockey Fights Cancer game are available now at the Scottrade Center Box Office or online at ticketmaster.com.
