The team officially announced that quarterback Tom Flores would miss the 1962 season while recovering from a lung infection and bronchiectasis, an abnormal widening of the bronchial tubes. His recovery was expected to continue for a few months and doctors expected him to be ready to go in 1963.

The team purchased the contract of quarterback Don Heinrich from the Dallas Cowboys for an undisclosed amount. They also signed a pair of free agents: guard Joe Parks of the University of Tulsa and running back Hal Lewis out of the University of Houston.
