Urlacher claimed that the tactic, known as 'diving', was common amongst NFL teams and even revealed that the Bears had a designated player to "get hurt" in a match.
"We had a guy who was the designated dive guy," the former linebacker told the Chicago Sun-Times.
Urlacher also said that the coach would give the designated player a signal to go down injured, adopting a diving motion that swimmers make with their arms.
The 35-year-old confirmed that the Bears were not trained on how to fake injury, but claimed that the tactic played a part in their game.
Urlacher retired at the end of last season having spent his entire 13-year career with the Bears.
