Ronald Araujo clashed heads with his own teammate, Gavi, midway through the second half.
Both players fell to the ground in pain.
Araujo was able to get up and back into position, but he fell to the turf once again when the referee’s whistle blew.
Players from both sides rushed to Araujo’s aid, including Sergio Busquets, who quickly called for medical attention.

Play was stopped for just under 10 minutes while Araujo received treatment. Gavi, meanwhile, was able to continue.
Barcelona have since revealed he has suffered a concussion and has been taken to the hospital to undergo further testing.
Everyone at GiveMeSport wishes Araujo all the best and a speedy recovery.
Barcelona were leading 3-1 at the time of the incident.
The home side went into the break with a two-goal lead thanks to strikes from Memphis Depay and Pierre-Emerick Aubameyang.
Aubameyang netted his second just after the break, only for Celta to reduce the deficit to two goals once again through Iago Aspas.
There were no further goals as Barca held on to a two-goal victory.
The Catalan giants remain in second having accumulated 72 points from their 36 games. They are seven points clear of Sevilla in third.
