An autopsy concluded that traumatic brain injury from a helmet-to-helmet hit during practice caused the death of a Frostburg State University football player last month, his father said Tuesday.

"Derek would want people to know this was an accident," he told The Associated Press in a telephone interview.

The university posthumously awarded him a bachelor of science degree with honors in liberal studies. Read more: http://espn.go.com/college-football...e-player-derek-sheely-death-according-autopsy
