AMES, Iowa--Josh Vaughan scored a game-high 22 points but his potential game-winning 3-pointer at the buzzer rimmed off as North Dakota State lost 73-71 at Iowa State in men's college basketball Saturday, Jan. 9, before a crowd of 12,937 at Hilton Coliseum.

Vaughan was 8-for-18 from the field and made 6 of 11 from behind the arc, one shy of the NDSU school record.  He has scored 50 points in the last two games for North Dakota State, which dropped to 5-10 with its sixth loss in seven games.

NDSU trailed by as many as 10 points early in the second half, but the Bison tied the game at 53 with 12:13 left on a Michael Tveidt basket that capped a 7-0 run.

The Bison went ahead 59-56 with 9:04 to play, but Iowa State (11-4) took back the lead with seven straight points.

Charles Boozer's steal and layup gave the Cyclones a 67-62 lead, but NDSU tied it at 67 inside the 3-minute mark with a Tveidt 3-pointer and two free throws by Austin Pennick, who was limited to six minutes in the second half with four fouls.

Lucca Staiger's third 3-pointer of the game put ISU up 70-67, and the Cyclones answered a Tveidt layup with another 3-pointer from Boozer that made it 73-69.

Pennick scored an open layup with 44.9 seconds left to make it a two-point game, and Iowa State missed a 3-pointer on its final possession to set up NDSU's last shot.

North Dakota State had a 47-39 rebounding advantage against the taller Cyclones, including 10 rebounds apiece from Tveidt, Eric Carlson and Sam Sussenguth, who matched a career high.

Carlson approached a triple double with 17 points and eight assists, Tveidt finished with 13 points, and Pennick scored 10.

NDSU shot 39 percent from the floor and was 7 of 19 from the 3-point line.  Iowa State shot 41 percent and was 9 of 18 from the arc.

The Cyclones were 12 of 21 at the foul line.  NDSU made 6 of 7 free throws.

Boozer finished with 19 points for Iowa State, preseason All-American Craig Brackins had 15 points, 11 rebounds and three assists, and Staiger finished with 10 points.
