Selected by the Packers in the second round of the 1960 NFL draft, Jeter began his pro career in the Canadian Football League with the British Columbia Lions. He was used in Canada as a running back in 1960 and 1961, backing up CFL legend and former Iowa teammate Willie Fleming. Still under contract in Canada, Jeter spent the 1962 season on the Packers' taxi squad, saw limited action as a wide receiver in 1963 and 1964, and was moved to defensive back in 1965.
