Soccer Overtime consists of two 15 minutes periods separated by a 1 minute break.
If the score is still tied after overtime, a penalty kick shootout will determine the winner.
Remember: Stoppage or “injury time” is the time added at the end of each 45 minute half and it depends solely on the referee’s criteria.
It’s meant to account for the time needed to reset after a goal, substitutions, assessment and treatment of injured players, and the referee can add time if he feels a team is wasting time on purpose.
Generally, throw-ins and corner kicks are not subject to stoppage time (unless the referee feels the team is doing it slowly to waste time).
