Colombia got off to a nightmare start on Tuesday when Carlos Sanchez was sent off after less than three minutes of their 2-1 defeat to Japan.
Carlos Sanchez was shown the second-fastest red card in World Cup history, according to Goal.
Sanchez blocked Shinji Kagawa's shot with his arm after just two minutes and 56 seconds, prompting the referee to brandish the straight red card.
Kagawa then put Japan ahead from the penalty spot but even with 10 men Jose Pekerman was able to make his side competitive and Juan Quintero levelled with a free-kick six minutes before half-time.

Pekerman brought on 2014 World Cup Golden Boot winner James Rodriguez in the second half but the Bayern Munich star, not fully recovered from a calf injury, was not allowed much of the ball by a disciplined, energetic Japan side.
Akira Nishino's men came into the tournament as one of the lowest ranked teams but they defied their position by making good use of their man advantage and fully deserved to have their lead restored when FC Koln forward Yuya Osako headed the winner in the 73rd minute.
Victory over Colombia will give Japan hope of progressing beyond the group stage for the first time since 2010, while Pekerman will hope that James can return to full fitness in time for their forthcoming clash with Poland.
