EUGENE, Ore. (AP) -- Oregon starting left tackle Tyler Johnstone has re-torn the ACL in his right knee and will be out for the upcoming season, according to a published report.
Johnstone told Comcast SportsNet that he will have surgery on Friday.
Oregon would not discuss the injury, per team practice, and offensive line coach Steve Greatwood told reporters that Johnstone was day-to-day.
Johnstone was coming back from surgery to repair the same ACL after he was injured during Oregon's 30-7 victory over Texas in last season's Alamo Bowl.
Last week at the start of training camp, Johnstone said he was hoping to start in the Ducks' season opener against South Dakota on Aug. 30. The junior has started 26 straight games for the Ducks.
He will likely be replaced by junior Andre Yruretagoyena, who practiced with the first team this spring after Johnstone's first surgery.
Oregon quarterback Marcus Mariota called Johnstone one of Oregon's spiritual leaders.
''It is unfortunate, we're praying for him, but he's going to work back to getting healthy and he'll still make his contributions to the team,'' Mariota said.
