Lionel Messi was replaced in the first half of Barcelona's LaLiga match against Sevilla with a concerning arm injury, placing his Clasico participation in doubt.
The Barcelona captain appeared to fall awkwardly after jumping for the ball, landing on his right elbow in the process.
He was treated at the side of the pitch for some time before eventually making his way down the tunnel with his arm strapped up.
Ousmane Dembele replaced the Argentina man, and Barcelona eventually won the game 4-2, but that was where the good news ended for Messi.
He was taken to hospital where x-rays revealed he has a fractured arm, keeping him out of action for at least three weeks. The Clasico comes next weekend, meaning Messi will sit that out, as well as the Champions League tie against Inter Milan.
