The Clemson community is in mourning after the reports of former running back C.J. Fuller died at the age of 22. There is currently not a reported cause of death and an autopsy will take up to six to eight weeks, according to ESPN.

Current coach of the Clemson Tigers released a statement on Fuller’s death:

“Our thoughts, prayers and deepest sympathies are with C.J.’s family. I’ve known C.J. a long time and watched him grow up through the Easley rec leagues [in South Carolina] all the way through Easley High School. I’m proud of what he accomplished as a Clemson Tiger, most of all his accomplishment of being a Clemson graduate. Our deepest condolences and the thoughts of our program are with his family this evening. May he rest in peace.”

TMZ reports a source close to Fuller states he attended physical therapy prior to his death. He returned home and went down, requested for water prior to being transferred to a hospital for treatment.

During his time at Clemson, Fuller assisted Clemson in winning the 2016 National Championship
