Douglas is set to sign with Washington on a one-year contract worth up to $3.8 million, Adam Schefter of ESPN reports.
Douglas started 13 of his 15 regular-season appearances with the Dolphins in 2025, totaling 62 tackles (37 solo), including 1.0 sacks, plus 13 passes defensed, including two interceptions, and one forced fumble. He will provide the Commanders with depth at cornerback while Trey Amos (lower leg) works his way back from a fractured fibula suffered in Week 10 of the 2025 campaign.
