Following up on news from Monday, D.C. United have made the acquisition of goalkeeper Charlie Horton official, obtaining his rights from the New England Revolution in a sign-and-trade deal. United sent an undisclosed amount of general allocation money to the Revs in the exchange.

Horton, 21, most recently played for Leeds United, where he signed a two-year contract last summer. Citing personal reasons and a desire to be closer to home, Horton and Leeds agreed to mutually terminate his deal so he could sign with an MLS club. He comes to a United side missing its starting goalkeeper Bill Hamid for several months and is expected to make a strong push to be included in the gameday squad once he's integrated into the team. When Hamid returns, Horton's position on the depth chart becomes a more interesting proposition. United would have four goalkeepers at that point, and should he wrest a start or two away from Andrew Dykstra we may see United having to make a very tough decision.

So, about 72 hours before D.C. kicks off their 2016 MLS Regular Season against the LA Galaxy in Carson, California, the roster would appear to be as set as it is going to be for the time being.
