Arena on month-long hiatus, scouting below the Mason-Dixon line

New York Red Bulls coach Bruce Arena is in Virgina scouting players at the school where he won 5 (count 'em y'all) national titles as a college coach. You can read a bidbit about it here. The article also mentions that he is on a month-long hiatus. Doesn't he have some empty roster spaces of the Designated Player variety to fill? Or maybe NYRB will have a rookie striker and midfielder next season?
