Manchester United striker Javier Hernandez could become an injury doubt for his club after suffering a knee injury while on international duty with Mexico.
The 25-year-old will undergo tests after he collided with Nigerian goalkeeper Vincent Enyeama during a goalless draw on Wednesday.
Hernandez told Univision: "I don't feel good, the goalkeeper fell on top of me, I'll wait for the tests."
Mexico national team doctor Jose Vazquez told ESPN Deportes: "We have to wait to see how it evolves and to run the relevant tests.
"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."
Hernandez has struggled to secure a regular spot in manager David Moyes's first team this season.
