Jozy Altidore's final showing before the World Cup -- a two-goal outing against Nigeria in a June 7 friendly -- led plenty to believe that he was in for a big tournament in Brazil.
The U.S. forward's time in Brazil might be over after just 21 minutes, though.
Altidore pulled up lame trying to track down a Michael Bradley pass down the left sideline, immediately grabbing his left hamstring. As trainers tended to him on the field, Altidore covered his face with both hands, continuing to do so as he was stretchered off the field.
Altidore was replaced by Aron Johannsson, with the social media sphere immediately clamoring for the likes of Landon Donovan. One problem with that: The deadline to replace injured players has passed. According to U.S. Soccer, if Altidore is unable to go from this point on, the USA will go to battle with a 22-man roster.
A prognosis for Altidore has yet to be determined as he gets evaluated. The USA was leading 1-0 at the time of Altidore's injury, with Clint Dempsey scoring 30 seconds into the match.
Aside from Johannsson and Dempsey, Chris Wondolowski is the lone forward remaining on the U.S. roster. Donovan, Eddie Johnson and Terrence Boyd were among the cuts prior to Klinsmann's 23-man roster selection.
