American football cornerbacks

Lowell Wagner (August 21, 1923 – September 26, 2005) was a professional American football cornerback in the All-America Football Conference (AAFC) and the National Football League (NFL). He played eleven seasons for the AAFC's New York Yankees (1946–1948) and AAFC and NFL's San Francisco 49ers (1949–1955).
One of Wagner's greatest games was the final game of the 1951 season, when the 49ers beat the Detroit Lions 21-17 at Kezar Stadium. Wagner intercepted three passes, two leading to 49er touchdown drives, and the third stopping a Lions drive in the fourth quarter. The loss knocked the Lions out of the National Conference race and allowed the Los Angeles Rams to win the Conference title.

Albert "Al" Nelson (born October 27, 1943) is a former professional American football cornerback in the National Football League (NFL) for nine seasons for the Philadelphia Eagles. He played college football at the University of Cincinnati and was drafted in the third round of the 1965 NFL Draft. Nelson was also selected in the ninth round of the 1965 AFL Draft by the Buffalo Bills.
On September 26, 1971, in the first Eagles game at the newly-opened Veterans Stadium, Nelson scored a fourth quarter touchdown on a then-record 102-yard return of a missed field goal by Dallas Cowboys kicker Mike Clark. It was the Eagles' only score of the contest in a lopsided 42-7 loss. The previous holder of the record was his coach at the time Jerry Williams. In the previous off-season, the league had allowed missed field goals kicked into the end zone to be returned.
He is also a member of the Beta Eta chapter of Kappa Alpha Psi fraternity.

Jim 'Butch' Duncan (August 3, 1946 – October 21, 1972), was a professional American football defensive back. He played for the Baltimore Colts and New Orleans Saints between 1969 and 1972. He started in Super Bowl V for the Colts. He was found to have committed suicide with a policeman's revolver in 1972.
