USMNT manager Mauricio Pochettino acknowledged Pulisic also had a knock that he got in training prior to the match and pulled the forward due to managing the injury.
"He received a knock two days before today in a training session," Pochettino said. " I hope it's not a big issue, but when finishing the first half, when it [the injury] starts to get cold, you cannot work."
Still, the Argentine hopes his star will be back in action in a week's time against Australia.
"Hopefully, it's not a big issue...hopefully, the next game he will be available."
