Collins reverted back to the Patriots' practice squad Tuesday.
Collins was elevated to New England's active roster prior to Monday night's matchup against the Bears, where he eventually failed to record any stats despite logging 22 defensive snaps and five special teams reps in the contest. The 33-year-old has suited up for a combined 13 games over the past three NFL seasons, and he'll now return to the team's practice squad as an emergency depth option.
