GRAND RAPIDS (WZZM)- The 2012 Transplant Games of America are underway in Grand Rapids.

Opening ceremonies at Van Andel Arena Saturday night set the stage for the three day competition, involving 1,100 athletes who are alive today because of transplant surgeries and living donors. The athletes are representing 48 states in 12 sports.

"These people are here to help celebrate Grand Rapids along with organ donation and transplantation, so it's great for the city. Everybody's been raving about what a great city it is, and we're just so excited to have [the games] here," said Bill Ryan, chairman of the Transplant Games of America.

The five day event is expected to inject $2 million into the local economy. The 2012 Transplant Games of America run through Tuesday.
