Sims (concussion) is inactive for Sunday's Week 7 tilt versus the Bills, the team's official site reports.

EDGE Analysis

Sims suffered the concussion in last Sunday's victory over the Steelers and did not practice at all this past week. His absence, combined with that of Jordan Cameron's (concussion), leaves MarQueis Gray and Dominique Jones as the Dolphins' tight ends for the Week 7 contest.
