Demps is not eligible to return under the new injured-reserve rules.
Patriots coach Bill Belichick confirmed that rookie running back Jeff Demps is done for the season after being placed on injured reserve Friday.
There was some confusion about Demps' status since the NFL instituted a new rule that allows teams to place one player on short-term injured reserve, but Demps would have had to remain on the 53-man through Tuesday to be eligible.
Demps, who won a silver medal as a member of the U.S. 4 x 100 relay team at the Olympics, suffered a leg injury against the Giants in the preseason finale. He is signed through 2014.
