Ike signed a four year deal according to both Adam Schefter and LaCanfora's twitter accounts.
From the PG:
All along the Steelers privately expressed confidence that they would re-sign Ike Taylor and tonight they came through by agreeing to a four-year contract with their best cornerback over the past decade. Money terms were not immediately available.
Taylor, who told one member of the organization early this week that he would be back, will return for his ninth season. He cannot officially sign his contract until 6 p.m. on Friday and cannot join his teammates in practice at training camp until Aug. 4, per a new rule under the collective bargaining agreement.
