Washington placed Sims (toe) on injured reserve Friday.
The 23-year-old has been unable to practice since attempting to play through the toe injury Week 3. The move to IR will prevent Sims playing in any of Washington's next three games, making him ineligible to suit up again until at least Nov. 8 against the Giants. While Sims is sidelined, Dontrelle Inman (foot) should continue to work as Washington's No. 2 wideout, with Isaiah Wright the next man up.
