Thomas Davis is reuniting with head coach Ron Rivera.
Davis became one of the NFL's most respected linebackers during his 14-season stint with the Carolina Panthers from 2005-18. Under Rivera, who coached the Panthers from 2011-19, Davis was voted to the Pro Bowl three times (2015-17) and was named a first-team All-Pro once (2015).
He was released by the Los Angeles Chargers last week after one season, in which he led the team with 112 tackles.
The soon-to-be 37-year-old has amassed 1,210 tackles, 29 sacks, 18 forced fumbles, and 13 interceptions over his career.
The 3-13 Redskins featured one of the league's worst defensive units last year, allowing 146.2 rushing yards per game. Washington also reportedly re-signed linebacker Jon Bostic on Monday.
