SAN DIEGO (AP) — After earning a share of the Mountain West Conference title for the first time since 1998, San Diego State will face BYU in the Poinsettia Bowl on Dec. 20 at Qualcomm Stadium.

The Aztecs (9-3, 7-1) finished the regular season on a seven-game winning streak to share the conference title with No. 20 Boise State and Fresno State. San Diego State is just two years removed from its last Poinsettia Bowl appearance, a 45-17 victory over Navy in 2010.

"The Poinsettia Bowl is one of the best events I have ever been involved with, and it will be a tremendous experience for our student-athletes," said SDSU head coach Rocky Long. "Best of all, we will have the opportunity to play in front of our fans, and that will make for a great atmosphere."

The Cougars (7-5), an independent program, lost three regular-season games to ranked teams, including a 17-14 defeat to national championship participant Notre Dame. Four of the Cougars' five losses were by six points or fewer.

"Our team is anxious for the opportunity to continue to improve playing against a quality opponent," BYU head coach Bronco Mendenhall said.

The Poinsettia Bowl pits SDSU's powerful rushing offense, averaging 229 yards per game, against a BYU defense allowing just 14.7 points per game. BYU leads the all-time series against SDSU, 27-7-1.

The Poinsettia Bowl is sponsored by San Diego County Credit Union.
