Barcelona defender Ronald Araujo was taken off the pitch in an ambulance during their victory over Celta Vigo and rushed to hospital.
The Uruguayan was involved in a sickening clash of heads with teammate Gavi in the 62 minute. The two players went to challenge for a looping ball just inside their own half and accidentally collided. While Gavi stayed down, Araujo initially stayed on his feet and ran back to recover before suddenly dropping down to the turf in a worrying incident for the 23-year-old, marring the match.
Fans chanted "U-RU-GUAYO" form the stands following his substitution and a statement from the club read: "Ronald Araujo has suffered a concussion and has been taken to the hospital to undergo further testing." In his post-match news conference, manager Xavi Hernandez confirmed: "Araujo is conscious, out of danger. [The] doctor tells us not to worry."
