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.
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.
He will likely be replaced by junior Andre Yruretagoyena.
