Oregon quarterback Marcus Mariota, who was wearing a brace during the Ducks' 26-20 loss to Stanford on Thursday night, has a partial sprain of the MCL in his left knee, a school official acknowledged to Ivan Maisel of ESPN.com.
Spring practice looked very different for breakout stars such as Texas A&M QB Johnny Manziel and Oregon QB Marcus Mariota, who went from relative unknowns last season to two of the main attractions in college football heading into this season.
Oregon has built a coaching tradition where the Ducks promote from within, and the new guy does better than the old. It has seemed simple, until now. Can Mark Helfrich improve on what Chip Kelly achieved?
