Foster, who was a fifth-round draft pick of the Rams last year, was released by St. Louis on Sunday. He did not appear in a game for the Rams last season.
Fitzhugh was an undrafted free agent who was in training camp with the Jets last summer and later signed to their practice squad. Baltimore signed him off New York's practice squad in December, but he was inactive the last two games of the regular season.
