Ronaldo suffers head injury in Real win

Cristiano Ronaldo was forced to leave Sunday's 2-1 win
over Levante after injuring his head in a collision in the
opening minutes.

Levante defender David Navarro's elbow opened a gash
above Ronaldo's left eye that required treatment on the
sideline before returning to the pitch.

Ronaldo scored Madrid's opener in the 21st minute but
could not continue after halftime.

Jose Mourinho said that his star forward "lost vision in both eyes and couldn't go on."
