The Jets on Tuesday announced that they placed running back Bernard Pierce on injured reserve and signed running back Antone Smith to replace him.
Pierce had been dealing with a hamstring injury throughout training camp.
He was a long shot to make the final 53-man roster anyway, because the Jets already had Matt Forte (who has a hamstring injury of his own), Bilal Powell, and Khiry Robinson ahead of him on the depth chart.
The Jets' other current running backs are also roster long shot guys: Terry Williams, Dominique Williams, and Romar Morris, plus Smith.
