SportsCenter anchor Stuart Scott passed away Sunday morning at the age of 49 after battling cancer.
Scott was diagnosed with cancer in November of 2007, and ESPN reports that he had undergone several surgeries, chemotherapy, radiation and clinical trials in his fight against the disease.
Joining ESPN in 1993, the anchor became known for his enthusiasm and catchy phrases like "Boo-ya" and "As cool as the other side of the pillow."
In Memoriam: Stars We Lost in 2014
Scott is survived by his two daughters, Taelor, 19 and Sydni, 15.
In July, Scott accepted the Jimmy V Perseverance Award at the ESPYs, and in his speech, he told his teenage daughters: "Taelor and Sydni, I love you guys more than I will ever be able to express. You two are my heartbeat. I am standing on this stage here tonight because of you."
During the moving speech, his words were touching and inspiring, "When you die, that does not mean that you lose to cancer. You beat cancer by how you live, why you live, and the manner in which you live," Scott said. "So live. Live. Fight like hell."
Many stars have used Twitter to share their sadness over Scott's passing.
