Sanchez went to ground clutching his face after Fuchs threw the ball at his shoulder in the closing stages of the Gunners' 1-0 Premier League win over Leicester at Emirates Stadium on Wednesday.
The Arsenal forward had been trying to block Fuchs' attempt at a long throw as Leicester pushed for a late equaliser following Huth's unfortunate own goal in the 86th minute.
The incident led to a barrage of criticism of the Chile international, who appeared eager to explain his actions by posting a picture of himself on Twitter sporting a swollen lip in the home dressing room.
Feliz por la victoria pero termine con el labio hinchado happy for the victory but ended up with a swollen lip pic.twitter.com/0y301Ztnp9— Alexis Sánchez (@Alexis_Sanchez) April 26, 2017
Huth has now issued a sarcastic response by tweeting an image of his own post-match wound: a minute cut on his finger.
Arsenal boss Arsene Wenger defended Sanchez's actions in a news conference on Friday, insisting he did not find them "embarrassing".
