MANCHESTER, N.J. (AP) — Authorities say a pickup truck driver attempting to push a disabled vehicle onto a trailer was struck and seriously injured when the pickup rolled over him.

Manchester police say the accident happened around 6:30 p.m. Wednesday.

They say township resident Robert Bading Jr. got the vehicle onto the trailer and parked the pickup partially on the trailer's ramp. He then got out of the pickup to secure the other vehicle, but the pickup rolled backward and knocked him down, and a rear tire rolled over his head.

Braden suffered serious head injuries and was flown to a hospital. He remained there Thursday in serious condition.

The accident remains under investigation.
