Per NFL.com, the Chicago Bears have signed free agent WR Markus Wheaton.
Wheaton, a 2013 third-round pick of the Steelers, played his first four NFL seasons in Pittsburgh. He caught 44 passes in 2015 for a career-high 749 receiving yards and 5 TDs.
He played in three games last season before a shoulder injury landed him on IR.
Wheaton is known for his speed but has lacked consistent production throughout his career. He served as Pittsburgh's main kick returner in 2014, returning 20 kicks, but has returned just five kick the last two years combined.
Wheaton will likely serve as Chicago's No. 2 or No. 3 wideout, alongside Kevin White and Cameron Meredith, although not with Alshon Jeffery, who signed today with the Philadelphia Eagles.
Wheaton played in the 2013 Senior Bowl with QB Mike Glennon, whom the Bears are expected to soon shortly.
The team has not yet officially announced the Wheaton signing.
