The Chicago Tribune first reported the roster move.
Iglesias, the No. 99 overall selection in the 2009 NFL draft, spent the entire 2010 season on the Bears' practice squad, after being cut by the team on Sept. 4.
The receiver was inactive for all but one game during his rookie campaign, and finished 2009 with zero catches and one special teams tackle.
Following an impressive four-year run at Oklahoma, Iglesias arrived in Chicago with the reputation of being a big, physical receiver. However, the wide out struggled to adapt to the speed of the NFL game in the 2009 offseason, and made the Bears' 2009 final 53-man roster primarily because of draft status.
Iglesias had a much better showing this past offseason, but was unable to beat out Rashied Davis for the final receiver spot because Davis is a core special teams contributor. Iglesias cleared waivers and was brought back on the practice squad, and even though he was never promoted to the active roster, the Bears were pleased with his development.
Five members of the Bears 2009 draft class are no longer with the organization -- Iglesias (3rd round), defensive lineman Jarron Gilbert (3rd round), linebacker Marcus Freeman (5th round), safety Al Afalava (6th round) and wide receiver Derek Kinder (7th round).
