The Dolphins signed Cracraft to the practice squad Wednesday, Daniel Oyefusi of the Miami Herald reports.
Cracraft originally joined Miami on a one-year, $825,000 deal in February, but he was released as part of the team's final roster cuts Tuesday. The 27-year-old, who played 89 special-teams snaps over six games with the 49ers last year, now will look to work his way onto an active roster in 2022.
