It was the away side who took the lead through Nerijus Valskis' fine strike in the 26th minute. However, Jamshedpur denied Chennaiyin a win by coming up with an equaliser through Issac Vanmalsawma in the 89th minute.
With this draw, Jamshedpur find themselves in the fourth position with 12 points while Chennaiyin FC are still ninth with six points from seven games.
Jamshedpur had the first major chance of the game in the 13th minute when C.K. Vineeth found himself in acres of space down the left. He only had to find Passi or Farukh Choudhary inside the box. However, his cross was misdirected and the chance went abegging.
The breakthrough the away side desperately sought came in the 27th minute through Nerijus Valskis who bagged his fourth goal of the campaign. He got the ball on the edge of the box and found Rafael Crivellaro. The Brazilian passed it back to Valskis who took a touch and shot on the turn which hit the inside of the far post on its way into the goal.
Just after the half an hour mark, Jamshedpur were jolted when Noe Costa suffered a shoulder injury after a challenge from Masih Saighani and had to be substituted with Jitendra Singh taking his place.
The best chance for the home side came in the 38th minute as Choudhary squared it for Passi. However, the striker, under pressure from Eli Sabia, couldn't connect well which allowed Lucian Goian to clear the danger.
Jamshedpur coach Antonio Iriondo brought in Aniket Jadhav to replace Mobashir Rahman to fortify his team's attack after the break.
From a quick counter, Crivellaro sent Chhangte through but the left winger's tame shot went straight into the hands of Subrata Paul.
At the other end, Vishal Kaith was called into action in the 69h minute when Isaac Vanmalsawma's dink from the right looked headed for the top corner before the Chennaiyin goalkeeper pushed it out for a corner.
In the 89th minute, Aniket Jadhav showed silky skills to fox a couple of defenders and find Passi inside the box. He picked out Issac whose shot was deflected into the goal off Farukh Chowdhury, wrong-footing the goalkeeper.
