Shane Vereen is back on the shelf after the New York Giants running back suffered a second triceps injury, according to the New York Daily News' Seth Walder.
"Shane re-injured his triceps," Giants head coach Ben McAdoo said. "He worked his tail off to get back to where he was. I'm disappointed for Shane."
McAdoo added that the team is unsure when Vereen will be healthy enough to return.
The Giants placed the 27-year-old on injured reserve in September, and the initial worry was that he'd be lost for the entire season.
