What is Stoppage Time?

A professional soccer game lasts 90 minutes, split into two 45-minute halves. The team with the most goals at 90 minutes wins the game, however there is something called 'stoppage time' that comes into play at the end of regular time. Unlike many other sports, games are timed on a running clock. At the end of each half, the referee will add on stoppage time to play, which is roughly estimated to account for delays in play during that half.
