The Steelers came to terms with two more draft picks, including second-rounder Mike Adams.
Adams, an offensive tackle from Ohio State, reached his agreement Tuesday night on a four-year contract. He is the highest draft pick of the four who have come to terms.
Earlier, the Steelers and wide receiver Toney Clemons, the first of their four seventh-round draft picks, agreed on a deal.
Four draft choices have signed contracts with the team, all for four years, which is the required length for all draft choices, plus a fifth-year club option for those picked in the first round, according to the new collective bargaining agreement.
Clemons played at Valley High School in New Kensington. He attended Michigan, then transferred to Colorado.
