Back in December, Hall of Famer Rod Carew received a heart and kidney transplant after suffering a massive heart attack in September 2015. He had been living with a mechanical device that pumps blood in the meantime.

Earlier this month we learned the heart and kidney Carew, now 71, received came from former NFL player Konrad Reuland. Mary Reuland, Konrad's mother, did the research on her own to discover her son's organs were donated to Carew.

She recently sat down with Carew and was able to listen to her son's heartbeat through the Hall of Famer. Here is the heartwarming video:

"It was miraculous. It was just a wonderful thing to be able to hear a part of my son still here on Earth," said Mary Reuland to NBC Nightly News.  

Konrad suffered a brain aneurysm and passed away in December at age 29. A few days later his organs were donated, including his heart and a kidney to Carew. Reuland played for four NFL teams from 2011-16.

"He wanted to always help other people and that's the way he lived his life," added Mary. continuing, "I feel that in some divine way Konrad is up there directing where his parts went. His kidney went to somebody wonderful as well, and I'm sure his liver did too. So he saved some more people."
