Brown didn't play in 2017 after being waived by Denver before the start of the regular season. He last saw regular season action while with the Ravens in 2015, recording 112 yards on 14 catches in 10 games. He'll be looking to get a spot near the bottom of the Bears' receiver depth chart in 2018.
Brown was waived by the Broncos on Saturday, Mike Klis of 9News Denver reports.
Brown wasn't able to separate himself from a crowded Broncos receiving corps. He'll re-enter free agency in hopes of landing with a team in need of size at receiver.
Brown recorded one catch for 15 yards in his return. It was his first action since being placed on the injured reserve with an undisclosed injury in December of last season. While the practice squad figures to be his likely destination, he will look to impress as the preseason progresses.
