One of the deadliest college football Saturdays in decades has added to one of the deadliest college football years in decades. Midwestern State cornerback Robert Grays died Tuesday after suffering an apparent serious neck injury while making a tackle Saturday against Texas A&M-Kingsville, the school confirmed early Wednesday. Grays was one of two college football players to die Saturday and the fifth this year. Prior to Saturday, there had been five deaths total "directly due to [college] football" since 2002, according to the National Center for Catastrophic Sport Injury Research. The last time two college players died in the same year playing the game was 2011, according to the NCCSIR. When medical examinations are finalized, two may have died on the same day Saturday.

No immediate cause of death was determined. Geib's organs were being donated.
