EUGENE — Oregon has lost a linebacker for the season.

Sophomore Adrian Jackson, the backup at strong-side linebacker behind La’Mar Winston Jr., suffered a foot injury late last week and he will miss the 2019 season, Oregon coach Mario Cristobal announced Monday.

Jackson had 13 tackles with one for loss in 12 games last season and was vying for a bigger role this fall.

With Jackson out, Oregon will turn to true freshman Mase Funa to fill the role.

Funa, who is coming off missing his senior season in high school due to a torn anterior cruciate ligament, had one tackle for loss on a critical third-and-two during the fourth quarter of Oregon’s 27-21 loss to Auburn.
