DE Williams signs $16 million, 2-year deal with Dolphins

MIAMI (AP) — Free agent defensive end Mario Williams has signed a $16 million, two-year contract with the Miami Dolphins.

Williams signed the deal Tuesday, a week after being released by the Buffalo Bills. He paid a visit over the weekend to Miami.

The Dolphins sought reinforcement at end because they may lose defensive end Olivier Vernon in free agency, and the status of four-time Pro Bowl end Cameron Wake is in doubt, too.

The pass rush could use an upgrade — Miami tied for 25th in the NFL with 31 sacks last season. Changes up front are part of a revamping of the defense under new coach Adam Gase.
