Morgan was arrested at Cities Restaurant and Lounge in the early hours of Sunday morning after allegedly punching a valet driver in the face.
The 28-year-old, who joined the Bears on a one-year contract from the Washington Redskins earlier this month, denies any wrongdoing and insists that he is "not worried" about the situation.
"I didn't touch him. I didn't do anything. This is crazy. I'm not worried about nothing. I have always been a stand-up guy in the community. Nothing like this has ever happened to me," Morgan told WRC-TV.
Morgan caught 20 passes for a career-low 214 yards last season having led the Redskins with 48 receptions and 510 yards in 2012.
