Oregon got bad news with the loss of Tyler Johnstone for the year Monday.Eugene, Ore. -- The Oregon football program got bad news Monday when head coach Mark Helfrich and his team were informed of a season-long injury to junior tackle Tyler Johnstone, sources tell DuckTerritory.com.

Johnstone reinjured the knee he hurt in the 2013 Alamo Bowl and will be forced to miss the entire 2014 season. DuckTerritory.com sources believe he has retorn his ACL for the second time in less than a year.

The 6-foot-6, 289-pound tackle out of Chandler, Ariz. started 26 straight games for the Ducks in his first two seasons, and was expected to make a full recovery from his Alamo Bowl injury in time for the Michigan State game Sept. 6.

Johnstone was an honorable mention selection by Pac-12 coaches in 2013, and was poised for a potential All-American caliber season in 2014.

The loss is a tough one for the Ducks, but they return four other starters from last season's team. Fellow junior Andre Yruretagoyena is expected to replace Johnstone at left tackle. Junior college offensive lineman Haniteli Lousi could also end up seeing some time at tackle.

One other option could be moving senior tackle Jake Fisher from right tackle to left, and insert either Yruretagoyena or Lousi in at right tackle.

We will have more on this report later.
