Falk (wrist) has been ruled out for Sunday's game against the Bengals, Adam Beasley of the Miami Herald reports.
Falk was a full participant in practice this week before being held out of Friday's session with an apparent wrist injury, but the Dolphins offense won't miss him in Week 5 with Ryan Tannehill drawing the start at quarterback. If Tannehill were to go down, however, Brock Osweiler and David Fales are slated to provide additional depth.
