Javier Hernandez took part in training on Wednesday (AEST) to hand Mexico a fitness boost ahead of its FIFA Confederations Cup semi-final against Germany.

Hernandez worked away from his team-mates on Tuesday (AEST) after suffering from muscular fatigue.

His absence was described as precautionary and so it proved as the 29-year-old striker went to work with the rest of Juan Carlos Osorio's squad in Adler.

Mexico faces Germany at Sochi's Fisht Stadium on Friday (AEST) and the ex-Manchester United favourite will be a familiar face for many of the opposition, having plied his trade in the Bundesliga with Bayer Leverkusen for the past two seasons.
