Kacmarek (undisclosed) is considered week-to-week as of Saturday, Barry Jackson of the Miami Herald reports.
Kacmarek did not play in Friday night's preseason finale against the Falcons. The rookie third-rounder played in the first two preseason games for the Dolphins, catching his sole target for three yards. The tight end is set to be the No. 2 option behind Greg Dulcich once the former regains his health.
