Tiger Woods is returning to the Memorial, where he is a three-time winner. He has skipped the tournament two of the last three years because of family matters and knee surgery.
Woods has not won at Muirfield Village, where Jack Nicklaus is the tournament host, since winning his third in a row at 2001.
He did not play in 2006 because of his father's death. Last year, he was recovering from the first of two knee operations that ultimately caused him to miss the second half of the season.
The Memorial will be played on June 4-7, with Masters play-off loser Kenny Perry the defending champion.
