Williams, 25, is a former third-round pick of the Ravens back in 2017. He’s currently in the third year of his four-year, $3.39 million contract and stands to make base salaries of $690,000 and $790,000 over the final two years of the agreement.
The Ravens made the decision to move on from Williams last month and he was later claimed by the Packers.
In 2019, Williams has appeared in four games for the Ravens and recorded two tackles and no sacks.
Campbell, 27, is a former fourth-round pick of the Browns back in 2015. He was in the third year of his four-year, $2,792,008 contract when Cleveland decided to waive him with an injury settlement in 2017.
Campbell signed on with the Texans but was among their final roster cuts in 2018. He had brief stints with the Cowboys and Jets before he was waived and later claimed by the Packers.
Green Bay brought Campbell back this past August only to place him on the PUP list soon after.
In 2018, Campbell appeared in eight games and recorded 19 tackles, no interceptions and a forced fumble.
