Manchester United winger Alejandro Garnacho will be sidelined for several weeks after suffering an injury in the 0-0 draw with Southampton on Sunday.
The 18-year-old came on after 73 minutes of the game and appeared to be in pain after a challenge by Kyle Walker-Peters.
Garnacho then went off and was replaced by Fred in the closing stages of the match at Old Trafford.
Walker-Peters suffered racist abuse online after the game at United.
A racist term was directed at the full-back in response to a comment about Garnacho.
In a post on Instagram, Walker-Peters said "the racial abuse I received is something that no player or person should ever have to experience".
