Tight end Johnny Mundt walked out of Oregon's practice again wearing a knee brace Tuesday, after icing the knee following Monday's practice. ... Defensive end Jalen Jelks wore a right knee brace and left practice alongside fellow end Justin Hollins, who also did not leave shoulder pads with managers following practice, indicating he didn't fully participate. The duo "were out there working their tails off today," Helfrich said. They play at a position already down the suspended Torrodney Prevot, and asked who is behind Hollins and Jelks on the depth chart Helfrich was circumspect, answering Oregon will "need all hands on deck, trying to get as many healthy bodies and guys getting reps."
