Chase Roullier suffered a fractured fibula on Sunday and was placed on injured reserve two days ago. He is expected to have surgery after getting a second opinion to assess any additional damage to his leg. Washington didn't add an offensive lineman on Tuesday, instead they activated rookie safety Darrick Forrest before his 21-day window expired for his return from IR.
News came out yesterday that DE Montez Sweat was also injured during Sunday's loss to the Broncos. He suffered a hairline jaw fracture, and is expected to miss 4-6 weeks. Washington did not officially place him on injured reserve yet, but that move will likely happen today.
