This morning, graduate student Marc Schaffer was on the sidelines at Temple football practice, where he is part of the training staff. Yesterday, he was helping save someone's life with his bone marrow. In 2008, Marc volunteered to become a donor, with a simple cheek swab at a campus drive. Last month, he got a call that he was a match for someone else — a boy with Hodgkin's lymphoma. “Once you get that call, it's no longer about you — it’s a family, a community, everyone’s affected by someone else’s decision,” he said. Coach Matt Rhule says the whole team was excited when they found out. “We're really proud of Marc that he would do something like this,” Rhule said.
