Gray is slated to start at tight end Sunday against the Bills, ESPN's James Walker reports.
Gray's promotion to Miami's starting gig comes in the wake of Jordan Cameron and Dion Sims both being ruled out with concussions ahead of Sunday's contest. While Gray boasts merely 15 receptions through four seasons, he's coming off a career-high 81 receiving yards on his three catches versus the Steelers last Sunday. He'll look to build on that momentum with another strong showing in an expanded Week 7 role.
