Cooper Manning (born 1974) is the eldest son of former professional football player Archie Manning and the brother of current professional football players Peyton Manning and Eli Manning. As an all-state wide receiver in high school, he planned to play at the University of Mississippi before being diagnosed with spinal stenosis, a medical condition that ended his playing career. He now works for the company Howard Weil as an energy trader.
Cooper Manning was born to Archie Manning and Olivia Manning in 1974 as their first child. From a young age, he held a more lighthearted view than his father. He played football for Isidore Newman School as a wide receiver and had a breakout year his senior year of high school with his brother Peyton Manning throwing all of the passes. Cooper was a highly ranked prospect out of high school and ended up signing with University of Mississippi which was Archie Manning's alma mater. When practices started in the summer before school, Cooper was feeling some numbness in his fingers and toes, so he went to the Mayo Clinic in Rochester, Minnesota, to get a diagnosis. The doctors told him he had spinal stenosis, a narrowing of the spine and pinching of the nerves usually seen in elderly people;  the diagnosis ended his football career. In honor of Cooper, Peyton donned his brother's jersey number, 18, when he (Peyton) began his professional career in the National Football League
