Uruguay striker Luis Suarez could once again be in trouble after appearing to bite an Italian opponent Tuesday in a key World Cup qualifying game.

The incident, shown on television replays, showed Suarez apparently bite the shoulder of Italy defender Giorgio Chiellini as the pair clashed in the Italian penalty area. It happened about a minute before Uruguay scored in the 81st.

Suarez was sanctioned with a heavy ban for biting Chelsea defender Branislav Ivanovic in the English premier League in 2013.

FIFA can sanction players for biting with bans of up to two years. Here is how twitter reacted to the moment:
