Marshall injured his right ankle during the season-opener, and his play has been uneven since. He had three touchdowns in Week 2 against the San Francisco 49ers, but only 48 receiving yards. During Monday night's win against the Jets, he had just six yards on one catch.
In three games this season, Marshall has 14 catches for 125 yards and four touchdowns. Last season he had 100 catches for 1,295 yards and 12 touchdowns. He has surpassed 1,000 receiving yards each of the past seven seasons.
Chicago also announced safety Chris Conte is questionable with a sprained left shoulder.
The Bears host the Packers at 1 p.m. ET on Sunday.
