The U.S. national team and Club Tijuana left back will be out for at least 10 days and will be reevaluated in two weeks, according to a club press release, following the injury suffered during Tijuana's 1-0 loss to Atlas. The incident occured in the 18th minute, when Atlas defender Leandro Cufre crashed into him, fracturing three bones in his face in the process.
Castillo persevered to play the remaining 72 minutes, which will be his last playing time for the time being. The injury timetable means that Castillo, who enjoyed two standout performances in the Copa Libertadores, will miss both of Tijuana's group stage clashes with defending champion and FIFA Club World Cup champion Corinthians in addition to Xolos' next league match against Queretaro at the very least.
The injury also calls into question Castillo's availability for the U.S. national team's upcoming World Cup qualifiers against Costa Rica and Mexico on March 22 and 26, respectively. Castillo was on Jurgen Klinsmann's roster for the first game of the CONCACAF World Cup qualifying hexagonal in Honduras last month.
