Redskins guard Arie Kouandjio will miss the entire 2018 season, multiple sources tell John Keim of ESPN.com (on Twitter). Kouandjio recently went under the knife to repair a torn quadriceps muscle, but he will take longer than expected to recover. 
Doctors tell the Redskins that Kouandjio will be out of action for six-to-eight months. That timeline should allow him to return in full health for 2019, but he won’t be able to partake in football activities for a while.
This marks a disappointing development for the Redskins as they were high on his offseason work up until this setback. Without Kouandjio, the Redskins will likely use the recently re-signing Shawn Lauvao as their starting left guard with Brandon Scherff mirroring him on the right.
The 2015 fourth-round pick out of Alabama has appeared in 17 games with Washington. Injuries decimated the Washington offensive line in 2017, resulting in three of its five Week 1 starters — Trent Williams, Spencer Long and Lauvao — missing at least six games. Kouandjio filled in as a starter in six of his eight games that season.
