Talks between NFL teams and Vonta Leach have heated up in recent days, The Miami Herald has learned, and Dolphins coach Joe Philbin is said to want a deal done by the end of the week.

Leach, an All-Pro Bowl fullback, has been on the free agent market since the Ravens cut him early last week. He visited the Dolphins during last week’s mini-camp, but left for home without a deal in place.

If signed, Leach would assumedly become the starting –- and possibly only -– fullback on a Dolphins offense that struggled in short-yardage situations a year ago. He has drawn interest from multiple teams.
