Porto midfielder Hector Herrera suffered a serious cut to his foot after a challenge with Juventus defender Stephan Lichtsteiner in their UEFA Champions League last-16 match on Wednesday.

The Mexico international was hurt shortly after the half-time restart as the Italian champions claimed a 2-0 victory in the first leg in Portugal.
Herrera was unfazed by the cut after the very late tackle by Lichtsteiner, and the 26-year-old recovered sufficiently to see out the match.
The Juventus player was booked for the challenge, which caused two gashes to the Mexican's foot.
Marko Pjaca and Dani Alves gave the Old Lady a precious first-leg advantage, leaving Porto a tough task to rescue their European dreams.
