This was an unbracketed game in the Las Vegas Invitational. Both teams will head to Las Vegas to play in different brackets.
Tennessee State: The Tigers were coming off a 72-57 loss at Texas Tech in which they trailed by just three points at halftime.
San Diego State: The Aztecs need to pick up their game if they’re going to come away with at least one win from their trip to Las Vegas. They play Creighton on Thursday night, with the winner to face the winner of the No. 12 Texas Tech-Iowa game on Friday night. SDSU won at BYU on Nov. 9 and also plays Utah in Los Angeles on De. 21. The Aztecs are looking for good results from those four games in order to improve their chances of an at-large NCAA Tournament bid if they don’t win the Mountain West Conference tournament.
Tennessee State plays Cal Poly on Thursday afternoon in Las Vegas.
San Diego State plays Creighton on Thursday night in the main bracket of the Las Vegas Invitational.
