Marvin Harrison has assured the Colts that he was not involved in the shooting that took place in his hometown of Philadelphia last month, according to The Indianapolis Star. "We look at everything seriously if we have an incident with any of our players. At the same time we want to make sure that we know what the facts are," owner Jim Irsay said Monday. Harrison reportedly had a conversation with Coach Tony Dungy and team President Bill Polian, insisting that he had no part in the incident. "It's an ongoing investigation, and we are following leads wherever they take us," Lt. Richie Brown, a Philadelphia detective, said. "Mr. Harrison is cooperating fully with the police department."
