The Miami Dolphins still need a free safety.
The Dolphins appeared on the verge of signing their second big free agent and filling another significant defensive need. They made Karlos Dansby the NFL's highest-paid inside linebacker over the weekend and were targeting Clark to help them lock down that swinging gate that plagued them last year between the yard numbers.
Last year's starting free safety, Gibril Wilson, was among three cuts Friday.
Clark led the Steelers with 110 solo tackles and tied for the team lead with three interceptions.
ESPN's Adam Schefter reports Clark agreed to a four-year contract to remain a Steeler. Palm Beach Post reporter Edgar Thompson adds the deal is for $17 million.
"He did some soul-searching," Clark's agent, Joel Turner, told Thompson. "He's entitled to change his mind. It's his life. ... We didn’t leverage anybody."
