Two attackers jumped a man on a Manhattan train early Tuesday, cops said. 

The victim was on a southbound 6 train at 96th Street and Lexington Avenue on the Upper East Side around 1:50 a.m. when the duo assaulted him, cops said. 

The victim suffered a cut on his head, police said. He was taken to Weill Cornell Medical Center with a non-life-threatening injury.

Police were unsure if the cut was inflicted by one of the suspects, or if the victim tripped and hit his head. 

Cops also did not know what led up to the attack. The suspects fled after the incident.
