The Denver Post reported Colorado Bureau of Investigation records showed McBean was arrested Friday, accused of stalking in Denver.
He posted $50,000 bond and is scheduled to appear in court Oct. 28.
"We are confident that the legal system will find Ryan completely innocent of any allegations," said Peter Schaffer, an attorney representing McBean.
"We will defend all allegations to the full extent of the law, as well as seek all legal avenues available to us when the claims prove to be frivolous," said Schaffer, who is also an NFL agent.
The Post did not provide details on the alleged stalking.
McBean attended team meetings and practice Monday.
Coach John Fox said the team is aware of McBean's arrest, which occurred on a bye week.
"We'll let the legal process run its course, but at this point, we're gathering information and, hopefully, the facts," Fox said.
McBean, a fourth-round pick of the Pittsburgh Steelers in 2007, signed with the Broncos in 2008 and has eight tackles and one sack this season.
