Shields is one of just four Rams who has played in the Super Bowl before. He finds the privilege even sweeter the second time around. In that big game against Pittsburgh eight years ago, Shields won a ring as an undrafted rookie defensive back making plays for Green Bay. He eventually became a Pro Bowl cornerback for the Packers before a fairly innocuous tackle in the 2016 season opener changed his life. (AP Photo/Jae C. Hong, File)

The Oakland Raiders have agreed to a four-year contract with free agent safety Lamarcus Joyner. A person familiar with the deal said Tuesday, March 12, 2019, on condition of anonymity, that Joyner will sign the contract after the start of the new league year. The person spoke on condition of anonymity because the move can't be finalized until Wednesday. (AP Photo/Jae C. Hong, File)
