Faced with Utah setting up a potential game-winning shot in the waning seconds of overtime, Dominic Artis tipped a pass intended for Dallin Bachynski to Damyean Dotson and he raced down the court for a breakaway dunk with 1 second left.
Dotson's basket sealed a 70-68 comeback victory in dramatic fashion and helped the Ducks remain unbeaten on Thursday night in the Pac-12 opener for both teams.
Richard Amardi had 14 points and Artis added 12 for Oregon (13-0, 1-0), which rallied from a 10-point deficit in the second half. The Ducks are off to their best start since winning 13 consecutive games to open the 2006-07 season.
