Before he was introduced Tuesday night at his charity event, Brandon Marshall had a video played featuring prominent sports personalities Warren Sapp of NFL Network and Stephen A. Smith of ESPN.
In the clips, Sapp calls Marshall a "retard" and Smith says that Marshall has multiple personalities.
Marshall has been clinically diagnosed with Borderline Personality Disorder, which affects at least 14 million in the United States.
"Our goal is to break these stigmas," Marshall told the crowd at Lucky Strike. "Borderline Personality Disorder is the most stigmatized disorder. I think it's a shame.
"If we raise awareness, we will see a change in our communities and in our lives."
The fundraiser Tuesday night was for Project Borderline, Marshall's non-profit. Teammates Jay Cutler, Brian Urlacher, Devin Hester, Johnny Knox and Israel Idonije were showed up, along with other sports celebrities like Gale Sayers and Dan Hampton.
"I was supposed to go to the Bieber concert tonight," Urlacher jokingly said. "He does a good job in the community. It's a good cause, and it's Brandon."
