An autopsy report states that ex-Clemson running back C.J. Fuller died of a blood clot that lodged in an artery in his lungs.

Pickens County Coroner Kandy Kelley said in a report released Tuesday that the 22-year-old Fuller died from a “Pulmonary thromboembolism and deep vein thrombosis.”

Pulmonary thromboembolism is when a clot breaks off in one part of your body and gets stuck in an artery in your lungs.

Fuller died on Oct. 3. He played three seasons with the Tigers and was part of Clemson’s national championship team in 2016.

Kelley’s report also said Fuller had surgery on his leg on Sept. 19, two weeks before he died.

Hello again, Utah State

Former Utah State coach Gary Andersen has returned to the Aggies.

Andersen previously was Utah State’s coach from 2009-12. He replaces Matt Wells, who had taken over the Aggies after Andersen’s first stint with the team. Wells was named head coach at Texas Tech last month.

Aggies co-defensive coordinator Frank Maile will remain Utah State’s interim head coach for its bowl game Saturday against North Texas.

Andersen left the Aggies to take the head coaching job at Wisconsin, then coached at Oregon State for two-plus seasons before unexpectedly stepping down in the midst of the 2017 season. He served as an assistant at Utah under coach Kyle Whittingham last season.
