The Houston Dynamo announced that D.C. United assistant coach Davy Arnaud and Michael Dellorusso have joined Wilmer Cabrera’s staff for the coming season. Arnaud, 36, was part of the coaching staff for D.C. in 2016 under Ben Olsen, retiring in March of 2016 after leaving an August 2015 game due to a concussion and not being able to return for the rest of the season. The move is the second in one week to come to the surface, with Amos Magee’s pending departure to Minnesota United, and would place Arnaud 90 minutes away from his hometown of Nederland, Texas.
