LOS ANGELES -- The Los Angeles Rams have agreed to terms with a couple of colleagues from Sean McVay's days with the Washington Redskins, hiring Aubrey Pleasant as defensive backs coach and Shane Waldron as tight ends coach, a league source confirmed to ESPN. Eric Yarber will be the new wide receivers coach after serving in that role for neighboring UCLA, the source confirmed.

The Rams aren't expected to announce the hirings until next week.

Pleasant, who will work under new defensive coordinator Wade Phillips, spent the last four years with the Redskins, working as an offensive assistant in 2013 before transitioning to defense, serving as an assistant who worked primarily with defensive backs. During his last two years in D.C., Pleasant worked under former defensive coordinator Joe Barry, who is being brought in to coach the Rams' linebackers. The Redskins wanted to retain Pleasant despite firing Barry and were reportedly getting ready to promote him to defensive backs coach, but the two could not work out a new contract.

Waldron spent last season as an offensive quality control coach with the Redskins. Prior to that, he worked four years at UMass, as a recruiting coordinator, tight ends coach and offensive line coach. Waldron also spent five seasons with the New England Patriots, as an operations intern (2002-03), operations assistant (2004), quality control coach (2008) and tight ends coach (2009).

Yarber has spent the last five years coaching wide receivers at UCLA. An L.A. product who won a Super Bowl with the Redskins mainly as a special-teams contributor in 1987, Yarber coached receivers with the San Francisco 49ers (2003-04) and Tampa Bay Buccaneers (2010-11). In between, he coached receivers at Washington and Arizona State.

Yarber takes over the role previously held by Mike Groh, who joined the Philadelphia Eagles. Pleasant replaces Dennard Wilson, who joined the New York Jets. Waldron's role was filled by John Lilly last year. The Rams have also agreed to terms with Greg Olson (quarterbacks coach), Bill Johnson (defensive line), Aaron Kromer (offensive line) and Chris Shula (defensive assistant). Special-teams coordinator John Fassel and running backs coach Skip Peete have been retained. The Rams have yet to settle on an offensive coordinator, but the role isn't necessarily a priority because McVay will call plays.
