The Packers had two open roster spots so there were no corresponding moves made.
Folston, 23, wound up going undrafted out of Pittsburgh back in May. He later signed with a three-year, $1.755 million contract with the Cardinals but was waived soon after.
The Titans signed Folston to a contract a few weeks ago only to cut him loose not long after.
During his four-year college career, Folston recorded 47 total tackles and 1.5 sacks in 28 games.
