It happened at the Second Avenue Station for the southbound F line at 1:20a.m. Saturday.
Authorities say a 58-year-old man was involved in a dispute with two others when it escalated and the victim was pushed onto the train tracks.
The victim did not make contact with a train or the third rail and was taken to the hospital where he is said to be stable.
Both suspects ran out of the station in an unknown direction.
Police are looking for two men in their 30s to 40s who were last seen wearing a blue hooded sweatshirt and a black jacket.
