"That was a lapse of judgment," Lurie said during his annual state-of-the-Eagles news conference. "Nothing he did was factually creating any wrongdoing.
"He shouldn't have been there. But he was trying to appease some people from his old neighborhood and family. So, let's give support. Let's not jump to judgment, and let's deal with the facts."
In his first public comments on the matter, Lurie referred to the "facts" of the incident 11 times in his 37-minute news conference, but he, like the NFL, refused to disclose what the team learned when it investigated the party and subsequent shooting.
"The facts are that there was no wrongdoing. If obviously that's wrong, that will become apparent. You can only deal with the facts. That's all you can deal with. I can't sit here and deal with rumors, innuendos, and all sorts of things. It's just not productive," Lurie said.
The owner was asked if he knew what interaction Vick had with Quanis Phillips, the man who reportedly was shot in the leg and who also was a codefendant in Vick's dog-fighting case.
"I don't know that whatsoever," Lurie said. "I'm just basing it on the investigations exactly that there was no wrongdoing. We have been over this already."
There have been multiple reports that Vick had a confrontation before the shooting that occurred in the early hours of June 25. Police have said Vick was not a suspect in the shooting, and he was not charged with any crime.
The prosecutor told the Associated Press that Vick was not involved in any "aggressive" conduct and extricated himself from the situation.
Vick refused to discuss details of what happened the night of his birthday party and what interaction, if any, he had with Phillips.
"I won't address the situation, what happened. Everything was put out there on the table from the beginning," he said.
