Ansu Fati left Barcelona's Copa del Rey match in tears on Thursday after sustaining an injury against Athletic Club in extra time.
The forward walked straight down the tunnel upon his exit in the last-16 match, which ended with Barca crashing out in a 3-2 defeat.
Fati, 19, only recently returned from a serious hamstring injury and missed most of last year with knee problems.
"Tomorrow we will see [about the extent of the injury]," Xavi told reporters. "He has been affected, but tomorrow we will see the diagnosis."
The manager added that Pedri, Gerard Pique and Jordi Alba also picked up knocks.
Fati was embraced by manager Xavi before disappearing down the tunnel.

Barcelona fought back to level at 2-2 in stoppage time, with Pedri providing the equaliser, but ultimately were defeated through a 105th-minute goal from Iker Muniain.
Fati had been introduced in the 61st minute as a substitute before his eventual departure.
