Christian Pulisic was substituted at half-time after scoring the winning goal for the United States against Iran in their Group B finale in Qatar on Tuesday.
The Chelsea winger was involved in a hard collision with Iran keeper Alireza Beiranvand shortly before half-time as he tapped in a headed cross from Sergino Dest to put the US up 1-0 -- a goal would that be enough to earn the Americans the win and second spot in the group.

Pulisic lay on the ground in the goalmouth for a few minutes before leaving the field and receiving attention from the team's trainers before coming back on and finishing the first half.
