A concrete worker on the 2nd Avenue Subway project was injured today when a piece of equipment fell on him. An FDNY spokesman says the unidentified worker sustained a serious injury to "a lower extremity" some ten stories below street level. The accident occurred at approximately 3:30 p.m. near 84th Street and Second Avenue.

NBC New York reports that rescuers "had to go underground and bring him over one block to the evacuation site at East 83rd Street, where they hoisted him above ground with a crane." The man was rushed to Cornell Hospital, where he's currently listed in serious but stable condition.

In March of 2013, a worker was stuck in the mud for hours at the site some 75 feet below street level—at one point he was stuck up to his chest.
