Barcelona were dealt a first-half injury blow in Wednesday's LaLiga encounter with Celta Vigo.

After just 20 minutes, João Cancelo hobbled off the pitch clutching his knee.

Following some medical attention, it was clear that the 31-year-old couldn't continue and was replaced by Alejandro Balde.

Cancelo appeared in clear discomfort as he exited the pitch and headed for the changing room.

A concerning sight for Barcelona's backline and for the Portugal national team with the World Cup on the horizon.
