He was taken to Bellevue Hospital and is expected to survive, the NYPD said. 

The suspect fled the scene and no arrests have been made. A motive for the stabbing was unclear. 

Thursday's violent incident comes amid a series of attacks in the city's subway system. Last week, a woman was stabbed in Washington Heights. Authorities said she was approached by a man asking for the time just after midnight on Feb. 10 at the 181st Street station on the 1 line. 

Hours later, a man allegedly tried to rape a woman on the E train in the Canal Street station. A suspect was later arrested. 

A day earlier, a man allegedly approached a 67-year-man on the platform of the 3 line at the 125th Street station on Lenox Avenue. He allegedly threw coffee at the victim and knocked a cell phone from his hand, causing an injury, police said.
