The regulation time of the match ended in a 2-2 draw.
Mridul Saikia drew first blood for the railmen in the first minute of the game, when he ruffled the Assam Rifles net after receiving a pass from the right flank.
However, the celebration in the Tinsukia Railways camp was shortlived.
Assam Rifles’ Jonny Khaklari equalised in the very next minute.
While L. Santa Singh put the Assam Rifles team ahead in the 40th minute, Parag Chamua equalised for the railway team just a couple of minutes later.
Into the second session, both sides made desperate attempts to veer the closely-contested match in their favour.
Tinsukia Railways had to fight it out with 10 men during the last 10 minutes of the match after the referee gave marching orders to Biju Gogoi for deliberately handling the ball in the restricted area.
