Manchester United forward Javier Hernandez will today find out the full extent of the knee injury he suffered while on international duty with Mexico last night.
Hernandez was unable to take to the field for the second half of Mexico's 0-0 draw against Nigeria after colliding with goalkeeper Vincent Enyeama.
The Manchester United man could face a prolonged spell on the sidelines if tests confirm he has suffered knee ligament damage.
He told Univision: "I don't feel good, the [Nigerian] goalkeeper fell on top of me, I'll wait for the tests."
However Mexican team doctor Jose Vázquez was quick to reassure Manchester United fans that the injury doesn't look too serious.
"We have to wait to see how it evolves and to run the relevant tests," he told ESPN Deportes.
"It's a blow, but we rule out the possibility of a knee ligament strain. There is only pain and there is no indication of instability in the knee."
The news will come as a blow to the Red Devils, who are already enduring a difficult season without the prospect of losing one of their strikers.
Hernandez has cut a frustrated figure at Old Trafford this season because of his lack of game time.
He's made just four Premier League starts under David Moyes this season, and reports have suggested he could be on his way out of the club in the summer.
