Linebacker Kyle Van Noy forced a fumble in the end zone and recovered it for a touchdown, and scored on a 17-yard interception return, both in the fourth quarter, to lead BYU to a 23-6 victory over San Diego State in the Poinsettia Bowl Thursday night in San Diego.

The big plays swung the momentum for the Cougars (8-5) in what had been a tedious defensive struggle. San Diego State (9-4), playing in the hometown bowl for the second time in three years, missed the chance for its first 10-win season since 1977 and had its seven-game winning streak snapped.
