Derby (foot) was a full participant in Wednesday's practice.
Derby has missed three consecutive games due to a foot injury, but his full participation in practice to begin the week suggests he has moved past the issue. Though the 27-year-old is listed as the Dolphins' starting tight end on the depth chart, it's unclear if he still holds that role after Nick O'Leary's impressive showing (four catches for 49 yards and one touchdown on four targets) in the Week 6 overtime win over the Bears. Rookie second-round pick Mike Gesicki lingers as another option at the position that could threaten Derby's snap count.
