Arizona Cardinals cornerback Jeff Gladney is dead at the age of 25. His agent said the former TCU player died in a car crash in Dallas early this morning. Gladney was a first round pick by the Minnesota Vikings in 2020. Fellow NFL player and former TCU teammate Jalen Reagor posted on Twitter "lost my brother, my best friend, my right hand man." Gladney played at TCU from 2015 through 2019.
