Dave Birkett Detroit Free Press Published 2:04 PM EDT May 16, 2019 When the Detroit Lions open the 2019 season on the second Sunday in September, they’ll be doing so against a rookie quarterback and a team that won’t have its best defensive player. Arizona Cardinals cornerback Patrick Peterson has been suspended for the first six games of the regular season, according to multiple reports, meaning the eight-time Pro Bowler will miss a game against the Lions on Sept. 8. Peterson reportedly was suspended for violating the NFL policy on performance-enhancing drugs. In six career games against the Lions, Peterson has two interceptions, according to Pro Football Reference. He’s widely considered one of the best cornerbacks in the NFL and has been the subject of potential trade rumors – some involving the Lions – since last fall. The Cardinals had the worst record in the NFL last season (3-13) and are in rebuilding mode. They have a new coach in Kliff Kingsbury, who was fired last season by Texas Tech, and spent the No. 1 overall pick in last month’s draft on Kyler Murray. Cardinals general manager Steve Keim has already said the team plans to use Murray, the reigning Heisman Trophy winner, as its starting quarterback this season. The Lions went just 6-10 last season, but they beat the Cardinals in Arizona, 17-3, last December for one of their wins. Contact Dave Birkett at [email protected] Follow him on Twitter @davebirkett.
