On Friday, the Dolphins opened up a roster spot by releasing LB J.D. Folsom who they had called up from the practice squad prior to last week's game against New England.
The open spot has been taken by TE Kory Sperry, who the team also called up from its practice squad.
Calling up Sperry may mean that Anthony Fasano's hip injury will sideline him on Sunday. If that is the case, Miami will have to rely on Joey Haynos and Sperry as the only two tight ends.
