Uruguay progressed to the round of 16 as Diego Godin's late goal secured a 1-0 victory over 10-man Italy -- but Luis Suarez could face a ban after appearing to bite Giorgio Chiellini on the shoulder.
The Azzurri went into the match ahead of their opponents on goal difference alone and the circumstances made for a cagey first half, with Uruguay -- in desperate need of the victory -- struggling to carve out chances.
Italy goalkeeper Gianluigi Buffon was forced to make a double save from Luis Suarez and Nicolas Lodeiro, but otherwise the main incident of note in the first 45 minutes was a Mario Balotelli caution that triggered an automatic one-match suspension.
As the match approached the final half-hour, Suarez's pass over the top found Cristian Rodriguez only for the Atletico Madrid man to send his shot well wide of the goal.
However, Uruguay's prospects were boosted soon afterwards as Claudio Marchisio received a straight red card for a dangerous challenge on Egidio Arevalo.
The 10 men were forced to desperately cling on, and Buffon was forced to make an excellent low save to deny Suarez.
There was controversy when the Liverpool striker appeared to bite Italy defender Chiellini on the shoulder, but the referee took no action.
Moments later, Atletico defender Godin headed home substitute Gaston Ramirez's corner to give his side a priceless late lead.
