LANSING, Mich. (AP) — The Michigan Lottery says it has been contacted by the winner of last week's $337 million Powerball jackpot.

In a news release issued Wednesday, the lottery says details about the ticket-holder won't be released until the prize is officially claimed. The release did not say if the Michigan Lottery has verified the winning ticket.

The Associated Press has left a message with Michigan Lottery spokeswoman Andi Brancato.

The winning ticket for the Aug. 15 drawing was sold at a Sunoco gas station in Lapeer, about 45 miles north of Detroit. The winner has one year to claim the prize.

It was the third-largest Powerball jackpot in the game's history. Lottery officials have said the winner could take home a $241 million lump sum.
