In June 1949, Hirsch alleged that the Hornets (the Chicago Rockets were renamed the Hornets in 1949) had breached a contractual obligation to pay him a bonus and sought a release to allow him to play for the Green Bay Packers. However, the Los Angeles Rams held Hirsch's NFL rights having selected him in the 1945 NFL Draft, and Hirsch was therefore unable to sign with the Packers. Instead, he signed with the Rams in July 1949. Hirsch earned $20,000 a year from the Rams, following a bidding war with the Hornets. However, after the 1949 season, the AAFC folded, and the Rams reduced his salary with the competition from the AAFC gone. During his career with the Rams, Hirsch never again attained the salary level he was paid as a rookie.
