Watch: Sunil Chhetri's Goal That Saw Kerala Blasters Forfeit Indian Super League Match vs Bengaluru FC

It was something unlike anything Indian Super League has ever seen before. A team walking out of a playoff match in Indian football's premier competition. At the centre of it was Sunil Chhetri, and his goal against Kerala Blasters for Bengaluru FC. All hell broke loose after Chhetri scored in the 97th minute from a free-kick, and a huge controversy followed. the Basters decided to walk out off the pitch and forfeit their all-important ISL play-off clash against Bengaluru FC, protesting against Chhetri's strike.

After a goalless stalemate during regulation time at the Kanteerava Stadium, Bengaluru FC took a 97th minute lead when the talismanic Indian captain converted a free-kick.

But the strike led to a full blown drama as the Adrian Luna-led side protested referee Crystal John's decision to declare it a legitimate goal, with counter-claims that he did not blow the whistle before Chhetri took the kick and the players were not ready.
