Tuesday was probably the coolest birthday of Madeline Swenson's life.

Swenson turned 10 and celebrated by announcing the Philadelphia Flyers starting lineup in their locker room, along with DJ Allen, before dropping the ceremonial puck before the Flyers Hockey Fights Cancer Awareness Night game against the San Jose Sharks.

Swenson, who is from Warminster, Pennsylvania, had acute lymphoblastic leukemia but finished her last chemotherapy treatment last week. She looked quite calm dropping the puck toward Joe Pavelski and Claude Giroux in front of more than 18,000 fans at Wells Fargo Center.
Allen, a 12-year-old from Philadelphia with Osteosarcoma, announced the goalies and defensemen before Swenson took over with the starting forward line. Each kid was given pounds by the players after their moment in the room.
