In 1948, Wojciechowicz lost the starting center job to Vic Lindskog, but appeared in 10 games, mostly on defense, for the 1948 Eagles team that shut out the Cardinals in the 1948 NFL Championship Game. In 1949, he appeared in all 12 games, but only one as a starter, as Chuck Bednarik was the starting center for the Eagles team. That year, the Eagles won their second consecutive NFL championship, shutting out the Rams in the 1949 NFL Championship Game.
