Stanford defensive lineman Terrence Stephens has been declared ineligible for the Rose Bowl against Wisconsin because of a secondary violation of NCAA rules related to his rental of off-campus housing.

The school declared Stephens ineligible Friday. The senior missed victories in the regular-season finale and the Pac-12 championship game against UCLA for what Cardinal coach David Shaw had called a "personal problem."

The 6-foot-2, 305-pound nose guard anchors the Stanford defensive line's run package, handling double teams to free up teammates to fill the gaps. Stephens has 10 tackles, one sack and one forced fumble this season. He also forced the win-clinching fumble by Curtis McNeal in Stanford's 56-48 victory in triple overtime at Southern California last year.

The school did not release any further details about his secondary violation.
