The COVID-19 list was created this summer for a player who either tests positive for or who has been quarantined after having been in close contact with an infected person or persons.
Players will remain on the list until they are medically cleared to return.
Campbell, 28, 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. From there, he had brief stints with the Cowboys and Jets before he was waived and later claimed by the Packers.
Green Bay brought Campbell back last year. He signed with the Titans this offseason on a one-year deal but was cut as the team trimmed its roster down to 53. He later landed on the Colts practice squad.
In 2020, Campbell has appeared in three games for the Colts, but has yet to record a tackle.
