The son of Green Bay Packers offensive coordinator Joe Philbin has been found dead in a Wisconsin river.

Authorities had been searching for Michael Philbin, 21, since he was reported missing Sunday night. He had been visiting friends in Oshkosh the previous evening and was last heard from around 2 a.m. local time Sunday, police said.

Divers recovered the body on Monday, but did not release the name until family members were notified.

Packers general manager Ted Thompson released a statement on Tuesday.

"The Packers family was saddened to learn of the passing of Michael Philbin, son of offensive coordinator Joe Philbin," Thompson stated. "Our thoughts and prayers are with Joe, his wife, Diane, and the Philbin family as they cope with their loss. This is an emotional and difficult time for them, and we ask that everyone respect their privacy. All of us in the Packers family share in their grief."

Foul play was not being suspected as of Monday night, although police are still investigating.

The tragedy comes with the Packers preparing to face the New York Giants in the NFC Divisional Playoffs on Sunday. It was unclear as of Tuesday afternoon if Joe Philbin would remain with the team this week or take a leave of absence.
