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.
Thompson, 27, is a former third-round pick of the Giants back in 2016. He spent just over two years in New York before the Giants waived him with an injury settlement in 2018.
Thompson later signed on to the Cardinals’ practice squad before the Cowboys added him to their active roster. He’s returned to Dallas two consecutive one-year contracts.
In 2020, Thompson appeared in 15 games for the Cowboys and recorded 42 total tackles, one interception, one pass defense, and one forced fumble.
Hamilton, 27, originally signed on with the Bills as an undrafted free agent out of Louisiana back in 2015. He was among their final roster cuts that preseason and quickly signed with the Packers’ practice squad.
Hamilton bounced on and off the Seahawks’ and Eagles’ practice squads until signing with the Chiefs in December of 2017. He was among Kansas City’s final roster cuts last preseason and caught on with the Cowboys briefly in October.
Hamilton signed a futures deal with the Cowboys for the 2020 season and landed on the practice squad after being cut coming out of camp. Dallas promoted him to the active roster back in October.
In 2020, Hamilton appeared in 10 games and recorded 10 total tackles and no tackles for loss.
