The summer transfer window is usually a time when MLS clubs add to their rosters. The Dynamo, however, lost two players before they could bring in anybody new.
Midfielders Leonel Miranda and David Rocha are leaving the club this week for separate reasons, leaving the Dynamo with 22 players on the roster for Friday's game at Orlando City SC.
Miranda had been on loan from Argentinian side Club Atletico Independiente. The loan expired June 30, and no deal could be reached.
Miranda started 14 MLS games and appeared in 32 matches overall. He scored three goals and had two assists.
