This year the Union haven't taken defender Keegan Rosenberry off the field and the rookie from Georgetown can't wait to return to action to atone for a difficult performance on Saturday.
Rosenberry, the only MLS field player to play every minute of his team's games this year, was responsible for allowing both goals in Saturday's 2-1 Major League Soccer loss at Portland
On the first goal, Rosenberry failed to cleanly trap a ball, then had it stolen by Darren Mattocks, who fed teammate Diego Valeri in front of the goal.
On the second goal, Mattocks blocked a Rosenberry pass and then sped toward the goal, taking several dribbles with Rosenberry defending, before sending a shot toward the far post that was tipped in by Fanendo Adi.
