A man is clinging to life after he jumped in front of a train in Manhattan Monday morning, according to authorities and police sources. 

The unidentified man was hit by an oncoming B train at the 47th–50th Streets–Rockefeller Center station just before 7:30 a.m., police said. 

No criminality is suspected, cops said. Police sources said he jumped in front of the train. 

The incident caused northbound B, D, F, and M trains to be temporarily delayed and rerouted. 

They resumed making regular stops more than an hour later, according to a tweet from the MTA.
