Pete Layden hit .250 in 41 games for the Browns in 1948, and played in the NFL 1948-50. After 1948 he played baseball with the Victoria Rosebuds, a semi-pro team in Texas which played in the Guadalupe Valley League. He has some baseball cards, but I'm not sure if he has any football cards.

There were a fair amount of NFL players who played semi-pro ball.

Dom Principe, NFL 1940-42 and 1946, played for the Bay Parkways in Brooklyn. Hall of Famer football player Ken Strong was a hard-hitting outfielder for the Springfield Greys. Probably some others who I'm forgetting.
