The Dolphins were back together at the Baptist Health Training Facility at Nova Southeastern University when the 2018 offseason program opened Monday.
Players began showing up early Monday for Phase One of the nine-week program, which will last until the middle of June.
Phase One lasts two weeks and activities are limited to strength and conditioning, as well as physical rehabilitation.
Phase Two follows the next three weeks and features on-field workouts that may include individual player instruction and drills and team practices conducted on a "separates" basis. No live contact is permitted, nor are offense vs. defense drills.
The final four weeks feature 10 days of Organized Team Activities (OTAs). No live contact is permitted, but 7-on-7, 9-on-7 and 11-on-11 drills are allowed.
The Dolphins' first OTA of 2018 will take place Tuesday, May 22 and the last will be Thursday, June 14. The Dolphins will have one mandatory minicamp for veteran players from June 5-7.
The Dolphins also will be able to hold a rookie minicamp either the first or second weekend after the NFL Draft, which is scheduled for April 26-28.
