MIAMI — Defensive end Jason Jones has signed with the Miami Dolphins, adding depth and flexibility to a front four that should be formidable next season.

The deal Monday was confirmed by the agent for Jones, Michael McCarthney. Jones is expected to back up another Miami newcomer, Mario Williams, and Cameron Wake, who is coming off Achilles tendon surgery.

Miami also added veteran defensive end Andre Branch this off-season.

Jones, who can also play tackle, started 31 games the past two seasons for the Lions. He'll be reunited in Miami with tackle Ndamukong Suh, a former Detroit teammate.

Suh, Williams and Wake are four-time Pro Bowl players. Miami sought upgrades in the line under new coach Adam Gase after tying for 26th in sacks and ranking 28th in run defence last season.
