Christian Pulisic Admits Half-Time Substitution in USA Win Was Just a Precaution

"I just got a bit of a kick in the first half, so I'm really hoping that it's nothing. Taking a little bit of precaution today. But I'm hoping I'll be fine in the next few days," said Pulisic.

The AC Milan forward is the US team's talisman, shouldering the weight of a nation's expectations as they try to make history with a deep run in a World Cup in which all of their games will be played on home soil.

Pulisic was a constant menace in a rampant first half, providing an assist as well as helping create Paraguay's own goal with a clever one-two with Weston McKennie.

But he was taken off at the half, and later told reporters he had received a knock in "the back of my leg."

"Sort of my (left) calf area. But I've had similar things before. I'm staying positive. I don't think it's anything at all."

Coach Mauricio Pochettino also said the forward was substituted because "we did not want to take any risks."

The US will hope Pulisic is correct, after the convincing win, with games ahead against Australia on Friday, and Turkey.

"An incredible start but there is a lot more that we still have to do," said Pulisic.
