The Bears on Tuesday placed second-year receiver Marquess Wilson on injured reserve with the designation to return and re-signed veteran nickel back Kelvin Hayden.
Wilson continues to recover from surgery to repair a broken collarbone he sustained Aug. 4 in practice. Starting in 2012, NFL teams have been permitted to reinstate one player placed on injured reserve back onto their active 53-man rosters each season.
The 2013 seventh-round pick was performing well in training camp and was expected to serve as the Bears' No. 3 receiver this season behind Pro Bowl starters Brandon Marshall and Alshon Jeffery.
During a question-and-answer session with fans on ChicagoBears.com Tuesday, general manager Phil Emery indicated that there is no clear-cut replacement for Wilson as the third wideout.
"I think you'll see the Bears use a number of multiple receiver sets and you will certainly see Josh Morgan, Santonio Holmes and Micheal Spurlock be part of those formations in any given game," Emery said.
Hayden returns three days after the Bears terminated his contract Saturday as part of final cuts. The Chicago native appeared in all 16 games with two starts in 2012, recording 40 tackles and one interception, before missing all of last season with a torn hamstring he sustained in training camp.
Hayden joined the Bears after spending his first seven NFL seasons with the Colts (2005-10) and Falcons (2011).
