The Miami Dolphins hope a couple of the team’s season-opening starters might return to the lineup in time for Sunday’s home game against the New York Giants. Receiver DeVante Parker and centers Michael Deiter and Greg Mancz, who have each started games this season for Miami’s troublesome offensive line, participated in a full week of practice, and are all eligible to come off the injured reserve list. The Dolphins have one vacancy on the 53-man roster, and the hope is that the team’s decision-makers will be able to regain at least one of those injured former starters.
