Chris Allen’s shot at the buzzer was blocked by Oklahoma State’s LeBryan Nash, and the ISU men’s basketball team was sent home with a 69-67 loss to the Cowboys.

The Cyclones were led in the back-and-forth game by Allen, who had 22 points on 6-of-9 shooting from 3-point range, and Royce White, who finished with 15 points, 12 rebounds and seven assists.

Oklahoma State took the lead for good with 4.7 seconds left when Nash hit a step-back, two-point shot over Allen.

With the loss, Iowa State drops to 17-7 overall and 7-4 in the Big 12. The Cyclones next face Texas A&M at home Saturday.
