The Green Bay Packers doubled-down on cornerbacks in the first two rounds of the 2018 NFL Draft, and now they’re both under contract.

Josh Jackson — pick No. 45 in the second round — signed his rookie contract Thursday with the Packers; Jaire Alexander — pick No. 18 in the first round — signed his deal earlier this week.

Jackson will wear No. 37 with the Packers. He led the nation in interceptions and passes breakups last season at Iowa, and turned pro after his junior year.
