UPDATE: Stanford Athletics has released 400 more tickets for students, in sections 139 and 140 of Stanford Stadium. After this allotment is sold out, students can purchase tickets starting at $40.

Stanford Athletics’ allotment of 4,500 student tickets for next Saturday’s home football game against Southern California has been fully distributed, according to GoStanford.com.

At 8 a.m. on Wednesday morning, ticket registration went live, and the system promptly crashed due to the volume of students attempting to log on.

By Wednesday evening, a number of students reported difficulties in acquiring tickets, and the link to USC student tickets no longer appeared on the “Student Tickets” home page on the Stanford Athletics website. On Thursday morning, the website confirmed that all tickets had indeed been sold out.

Students were notified of the need to register via a campus-wide e-mail on Tuesday.

Stanford Athletics implemented the system due to expectations of high attendance in light of the Stanford football team’s recent on-field success. The Oct. 9 game against USC is expected to sell out, so ticket buyers are expected to fill seats adjacent to the student section. When attendance is low, students can usually overflow into these sections with little difficulty, but since the game is likely to be fully sold out, there is nowhere in Stanford Stadium to place extra students.
