Indianapolis Colts owner Jim Irsay told the Indianapolis Star that receiver Marvin Harrison assured the team he was not involved in a recent shooting in Philadelphia.

Irsay said he hopes that's the case and told the newspaper, "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."

The Colts' security department has been in contact with NFL security in Philadelphia and with Philadelphia law enforcement agencies, Irsay said. He added, "We've done everything we could do in our diligence to try to discern what happened. He said he was not involved in that shooting and ... the authorities have said there is nothing imminent. You hope these things hold up to be true, that there won't be any charges and there wasn't any involvement."

Harrison also has told coach Tony Dungy and team president Bill Polian that he was not involved in the April 29 shooting in which a man was wounded in the hand. Bullet casings have been tied to a gun owned by Harrison.

Philadelphia police said last week that Harrison has been interviewed but is not considered a suspect in the case.

"It's an ongoing investigation, and we are following leads wherever they take us," a Philadelphia detective told the Star. "Mr. Harrison is cooperating fully with the police department."

The Colts' minicamp starts Friday, and Irsay said if Harrison doesn't participate, it's because his injured left knee isn't healed enough for drills. Irsay also described Harrison as "a tremendous asset to the franchise, both on and off the field."
