Kacmarek (undisclosed) was a full participant in Monday's practice, C. Isaiah Smalls II of the Miami Herald reports.
Kacmarek was considered week-to-week after the Dolphins' final preseason game against the Falcons on Aug. 28. The tight end has recovered from his undisclosed issue quickly and is back in action just in time for the team's Week 1 matchup with the Raiders.
