College football player's cause of death revealed after horrific helmet-to-helmet hit resulted in tragedy

A traumatic brain injury and a brain bleed are being blamed for the death of Southern Nazarene University football player Tyler Ulrich , who passed five days after a brutal helmet-to-helmet collision on October 10. According to a coroner's report obtained by ESPN, Ulrich suffered a 'subdural hematoma,' in which blood collects between layers of the brain. The school's original press release on his passing described Ulrich's cause of death as a 'traumatic brain injury,' but did not offer more details at the time.
