Dupuis has been diagnosed with a blood clot in his lung and will be out of the lineup for at least six months while undergoing treatment with blood thinners.The clot was identified during testing Monday, after Dupuis had complained of discomfort in his chest. “Pascal had a blood clot in his leg that traveled to his lung,” said Dr. Dharmesh Vyas, the Penguins’ team physician. "This is the second such incident that we know of for Pascal. The treatment is at least six months of blood thinners, during which time he will not be able to play hockey. Other than that, his condition is stable.” Dupuis previously was diagnosed with a blood clot in January 2014, shortly after he suffered torn ligaments in his knee. He was on blood thinners for six months while also recovering from surgery and rehabilitating his knee.
