Jacobs and Rogers also sat out Wednesday. Webster participated Wednesday on a limited basis.
Coach Tom Coughlin said Webster did not have a setback. "He's an every-other-day kind of a guy," Coughlin said.
Jacobs did stretch with the team at the beginning of practice, while reporters were allowed to be present. "Plus he did some running on the side," Coughlin said, "so we'll see when we get in there what the deal is."
On the bright side, linebacker Spencer Paysinger (ankle) practiced on a limited basis Thursday, after sitting out Wednesday.
NEW ADDITION: Coughlin confirmed that the Giants have added offensive lineman Dallas Reynolds to the roster, replacing Davis Baas, who was placed on injured reserve Wednesday. Reynolds spent a few days with the team earlier this month before being cut.
