The cause of death for a 15-year-old Mansfield High School student last week was internal bleeding from a ruptured spleen, according to the Tarrant County Medical Examiner.
John Moran died at 1:28 a.m. on Sept. 23 at Methodist Mansfield Medical Center. Mononucleosis, which may cause enlargement of the spleen, is listed as a complicating circumstance by the medical examiner.
Several news outlets including Fox4News.com had reported that Moran was injured while sparring with a friend, but police could not confirm.
In an interview with NBC 5, football coach Daniel Maberry said that Moran played in a junior varsity football game on Sept. 22 but was not injured.
“It was something that happened, an accident, after the game,” Maberry said. “I don’t know all the details of the whole situation. I know it was an accident.”
A message posted on the Mansfield High School football Facebook page said, “Our Tiger football family lost a precious player John Mark Moran last night in a tragic accident,” “Please keep his family, friends, teammates and coaches in your prayers.”
