Nottingham Forest defender Neco Williams was quickly taken to the hospital during their 3-1 win over Brighton.
The newly promoted club received a huge boost in their fight against relegation with the win.
However, their celebrations were marred by concern for Williams, who got into a nasty head collision in the game.
He collided with teammate Brennan Johnson during the second half of the game and had to come off.
Fans will be hoping that Williams can make a quick recovery and be back for their remaining games.
If he goes into concussion protocol, he may have to miss one or two upcoming matches.
