Peterson, an eight-time Pro Bowler over his 12-year career, spent the last two seasons with the Minnesota Vikings. He had five interceptions last season, the second-most of his career, to go along with 15 passes defended. However, Minnesota voided his contract earlier in March.
The Steelers’ addition of Peterson comes hours after cornerback Cam Sutton agreed to a deal with the Detroit Lions.
Peterson’s contract was voided by the Vikings. The 32-year-old had five interceptions in Minnesota last year, though, and Spotrac assigns a $6.4 million market valuation.
