Seattle Children's Hospital Patients Congratulate the Seahawks

— -- Seattle Children's Hospital hallways erupted in cheers and applause this weekend as the Seattle Seahawks played a nail-biter of a game against the Green Bay Packers and officially locked down their spot in Super Bowl XLIX.

And 8-year-old Maria Moore's room was no exception. The recovering leukemia patient watched the game while wearing her Seahawks hat and clutching her signed football. On the table next to her, she propped up a photo of herself with Seahawks quarterback Russell Wilson, who visited her at the hospital in November.

At one point, Maria was so bummed that her team appeared to be losing, she shed a little tear, her dad told ABC News. He told her not to worry, that Wilson and the Seahawks would come back. And they did.

"We were just totally shouting and applauding and hollering and giving high fives to each other," Thomas Moore told ABC News. "It was an amazing gave to watch. She was super excited."

Marie was diagnosed with acute lymphoblastic leukemia in September and initially didn't respond to chemotherapy, but the doctors at Seattle Children's and Fred Hutchinson Cancer Research Center helped get her treatment "recipe" just right, he said. Marie underwent a cord blood transplant on Jan. 2, and is in remission, but should be at the hospital a few more weeks, he said.

"We’ll probably be watching [the Super Bowl] from the hospital, but that's OK," he said. "As long as she's doing well, that’s fine by me."

Nearly every Tuesday, the team's star quarterback, Russell Wilson, visits Seattle Children's Hospital to meet with patients, said hospital spokeswoman Kathryn Bluher. So the team holds an extra special place in the hearts of patients and their families.

Wilson visited Maria the day after flying back from an East Coast game in November, and she was "all smiles," Moore said.

"It makes a bigger fan out of me. I really can't say enough," Moore said. "[Wilson] is a down to earth, really nice guy. He takes time talk to the kids, do pictures, sign some things."

After Sunday's win, patients at Seattle Children's Hospital took photos with "Congratulations" signs from their hospital beds to show their support.

"It takes their mind of things," Moore said. "It gives them something fun to think about."
