Police in Oshkosh say 21-year-old Michael T. Philbin of Ripon was last heard from around 2 a.m. Sunday. He had been visiting friends in Oshkosh that evening. He was reported missing on Sunday evening.
A police spokesman did not immediately return a message left Monday seeking additional comment.
A Brown County judge sentenced Michael Philbin to six months in jail in 2009 after he was convicted of sexually assaulting two young girls and two counts of battery.
His disappearance comes as the Packers prepare to face the New York Giants in an NFC playoff game Sunday in Green Bay.
