Hicks (undisclosed) was placed on the reserve/COVID-19 list Thursday.
It's not clear whether or not Hicks tested positive for the virus. He'll have a tight window to test out of COVID-19 protocols before the Bears play in Seattle on Sunday. Losing the behemoth would be a devastating blow to Chicago's defensve line, as Hicks has 3.5 sacks in eight games this season, including two in last week's loss to Minnesota.
