Washington will start a new safety Saturday night.
Junior Brandon McKinney is set to replace true freshman Cameron Williams against Arizona, a source close Williams confirmed to The Times this week. The 6-foot, 201-pound McKinney — who made his first career start in last season’s Rose Bowl loss to Ohio State — has made four tackles with a forced fumble in six games this season.
Williams, who started the first six games for UW, has made big plays — and mistakes — in the first half of his freshman season. The 6-0, 191-pound former high-school quarterback leads the Huskies with three interceptions but has also surrendered long touchdowns in back-to-back games.
