St. Brown is expected to sign a contract with the Bears on Thursday, Aaron Wilson of ProFootballNetwork.com reports.
St. Brown had a career-low mark in receiving yards last year, as he secured nine of 17 targets for 98 yards while rushing three times for 14 yards. The Bears lost Allen Robinson via free agency during the offseason, so St. Brown should have a chance to carve out a role behind Darnell Mooney in a re-tooling Chicago wideout corps.
