In Salvador, Edin Dzeko, Miralem Pjanic and Avdija Vrsajevic got Bosnia's goals for its first ever World Cup win and Reza Ghoochannejhad scored for Iran, which had to win and hope Nigeria lost to progress.

While the World Cup goal glut continued on the pitch, Suarez was again hogging headlines with his latest alleged biting incident.

If FIFA rules that Suarez sank his teeth into Chiellini's shoulder, it could suspend him for up to 24 matches or sideline him for a maximum of two two years. The Uruguay and Liverpool star is a repeat offender - he has twice been sanctioned for biting in his turbulent past, first in the Dutch league in 2010 when playing for Ajax and again in 2013 while in a Liverpool shirt. He also has been banned for racially abusing an opponent in England.

Suarez and the Uruguay football federation had until 5 pm local time (4 pm EDT/2000 GMT) to present FIFA with a documented case for the defense.

Meanwhile, tragedy struck in Nigeria before the country's clash with Argentina, as an explosion killed at least 21 people in a shopping mall in the capital, Abuja. Many shops at the mall have TV screens but it was unclear if the explosion was timed to coincide with the match, which started an hour later.
