ST. CLOUD, Wis. -- Some cheese-factory workers in Wisconsin said they hold Saturday's winning $208 million Powerball ticket.

A Wisconsin Lottery spokeswoman said no one officially claimed the jackpot as of Sunday evening.

She said it can take days or weeks for a winner to come forward.

But the group of about 100 workers at the Sargento Cheese plant in Plymouth said it has the winning ticket locked in a safe.

One of the workers, Eric Heimermann, said he planned to go to work Monday but said he wasn't sure what would happen after that.

"I thought it was a joke, but it turned out to be true," Heimerman told Milwaukee TV station, WISN.

Heimerman said he planned to buy a new Ford Mustang and celebrate with his fellow winners.

"We're going to pay off the bills and have a big party in St. Cloud," he said.

The winning ticket was sold at a convenience store in Fond du Lac along the town's so-called 'Miracle Mile,' where several multimillion-dollar lottery tickets have been sold in recent years.

The holders of the winning ticket will now have to decide to either take the 29- year, 30-installment annuity, or the one-time cash payment of $95,821,171.

The winning numbers drawn Saturday night were 2, 3, 9, 48 and 50 and the Powerball was 23.

Eight tickets matched five white numbers and won $200,000. The tickets were sold in Arizona, Colorado, Indiana, Kentucky, Louisiana, Minnesota, Missouri and Oregon.

Powerball is played in 29 states, the District of Columbia and the U.S. Virgin Islands.
