The tickets will remain on sale until they are sold out, although Staples added that the game has not sold out since 1986.
"We'll find a place to fit everybody in who wants to go," Staples said, "but you've got to order early if you want to sit by your class."
The Ticket Office has designated a large block of seats for each class, with first-years near the goal line and seniors closest to mid-field.
About 8,000 of the 31,000 available seats have been offered to Yale University, but Yale alumni, not students, will use the vast majority of these, Staples said.
"Last year, 2,600 Harvard students went down to Yale," he said. "There'll probably be the same number coming up from New Haven [this year]."
The price of tickets remains unchanged from last year at $12 for students and $25 for guests
