(Eugene, OR)  --  Number-13 Oregon will welcome UCLA to Autzen Stadium on Saturday.  Coach Mario Cristobal says the Ducks have focused on correcting turnovers and cleaning up tackling in practice this week.  Oregon is 2-and-0 while the Bruins are 1-and-1.  Also, the Pac-12 has reversed course and is now allowing nonconference opponents after multiple cancelations have already plagued the season.
