Stanford has confirmed earlier reports that defensive tackle Terrence Stephens will miss the upcoming game against UCLA to remain on campus and “take care of a personal matter.”

The senior from Gaithersburg, Md., is a big part of the Cardinal’s interior defense, starting seven of the team’s 11 games this season and all 13 last year. This year he has 10 total tackles, three tackles for a loss and a sack. He had a career-high five tackles, including two for a loss, and a sack in Stanford’s win over Oregon State two weeks ago.

Junior David Parry is the listed backup at nose guard and will likely fill Stephens place, although Stephens was still listed on the team’s depth chart as the projected starter as of Wednesday night. Parry did not see action as a freshman but was Stephens’ backup last season and recorded six tackles in limited action.

Stanford must beat the Bruins this weekend, or else hope Oregon loses to Oregon State, in order to secure a berth in the Pac-12 Championship Game as the Pac-12 North Division champion. The Cardinal would then host UCLA again next Friday night from Stanford Stadium with a Rose Bowl invitation on the line.
