A person with knowledge of the agreement says receiver Mike Wallace has agreed to a multiyear contract with the Miami Dolphins.
The person confirmed the agreement to The Associated Press on condition of anonymity because no deal had been announced Tuesday night.
In four years with the Pittsburgh Steelers, Wallace caught 32 touchdown passes. He gives the Dolphins the speedy deep threat they lacked last season, when their wideouts totaled three touchdowns.
The Dolphins' top priority at the start of free agency was to upgrade at receiver and provide another target for Ryan Tannehill, a rookie last year.
