Chickillo was placed on the list following his arrest earlier this month.
"Anthony Chickillo has been taken off the Exempt/Commissioner's List by the NFL Office, effective immediately," Steelers general manager Kevin Colbert said in a statement. "The League will continue to conduct an investigation of the incident, and we acknowledge that Anthony could still be subject to discipline by the League Office under the Personal Conduct Policy."
Chickillo was charged with assault, criminal mischief and harassment in Fayette County (Penn.) following a domestic dispute involving his girlfriend, Pennsylvania State Police confirmed to NFL.com.
He was arraigned when taken into custody, court records show, and Chickillo later was released on a $10,000 bond.
"I just want to acknowledge the situation has been a distraction for my teammates, the organization, and the fans. I apologize for that. I just want to do whatever I can to help the team and move forward. Just one day at a time and grow with my team. I am grateful no charges from the legal system. I am hopeful moving forward with the NFL they find the same thing."
