The 18th player taken in the January SuperDraft, New Zealand's Noah Billingsley "could have the same sort of impact" draft picks Chase Gasper and Hassani Dotson had last year, United coach Adrian Heath said.
Part of United's franchise dating to its NASL days in 2012, midfielder Miguel Ibarra turns a trial with defending MLS Cup champion Seattle into a contract after Loons did not bring him back after last season.
Loons starting left back fit and hopeful after month's training with U.S. Men's National team as well as items on Mason Toye's role, Brent Kallman's form, an Emanuel Reynoso update and United's strength of schedule.
Striker Mason Toye scored twice in the Loons' preseason-opening victory over Florida International University while coach Adrian Heath said the team's pursuit of Argentinian attacking midfielder Emanuel Reynoso is "in the pipeline."
The veteran Boxall getting his U.S. green card creates another open international spot for Minnesota United. Plus "signs are looking good" for United defender Chase Gasper to make his USMNT debut Saturday against Costa Rica.
