Christian Pulisic suffered an injury around 26th minute of the USMNT's friendly match against Australia.
The American forward of AC Milan, formerly of Borussia Dortmund and Chelsea, was forced off the field.
Pulisic appeared to struggle throughout the game until he got hurt, and Pochettino’s decision to start him is highly questionable. This has left the Milan club and head coach Allegri in a difficult and delicate situation ahead of the Serie A fixture against Stefano Pioli's Fiorentina.
"I think he (felt) something in his hamstring," Pochettino said after the match. "But tomorrow he will fly to Italy, tonight we will assess, and we will see. We cannot say (anything) at the moment."
Geria crunched Pulisic first in the 15th minute, as the USMNT star checked to the ball from his left-sided attacking position. A pass came into Pulisic’s feet, but Geria beat him to it, and Pulisic’s right ankle got stuck between Geria’s legs on the follow-through.
Pulisic stayed down for about 30 seconds after that tackle, clutching the ankle, then got back up as Pochettino jawed at the referee.
He played on, seemingly unaffected by the knock, until the 26th minute, when he spun past Geria in transition, as relayed via The Athletic As he broke away to run at the Aussie defense, 2-v-2, Geria clipped his lower leg from behind.
