(USA TODAY) -- A college student is making a huge sacrifice for a man he's never met.

University of New Hampshire senior Cameron Lyle is giving up the final two weeks of his track and field career to help save the life of a man he's never met.

Lyle, a thrower, is scheduled to donate bone marrow on Wednesday to a 28-year-old man suffering from acute lymphoblastic leukemia.

The surgery will limit his activities for weeks, meaning he won't be able to throw the shot put, discus or hammer at the final two meets of his career.

It wasn't a hard decision, he said in an interview with the Eagle-Tribune. "He has six months to live and I have the possibility to buy him a couple more years," Lyle said.

During his sophomore year, Lyle had his mouth swabbed to join the National Marrow Donor Program.

He was told this year that despite the slim odds of matching with an unrelated patient, the registry had found he was a 100% match with the man.

Lyle, a New Hampshire native, finished fifth in the shot put at the 2012 America East outdoor championships and second at the 2011 indoor meet.

He had been hoping to throw the shot put at the conference championships next month.

Lyle won't know the identity of his recipient for at least one year. There can be opportunities for meetings in the future, if both parties are willing.
