EAST RUTHERFORD, N.J. -- New York Giants defensive end Justin Tuck and running back Brandon Jacobs are listed as doubtful and center David Baas has been ruled out for Sunday's game against the Seattle Seahawks.
None of the three practiced during the portion of the session open to the media Friday.
Tuck, who is nursing neck and groin injuries, had practiced on a limited basis during the team's padded session Thursday, but he said that he was considering resting until the team's Week 7 bye.
Coach Tom Coughlin said Friday that Tuck had a setback, and is having more issue with his groin than his neck at this point.
"The groin is the irritating thing," Coughlin said.
Tuck practiced on Thursday with a different face mask and shoulder pads in an effort to limit the pain in his neck, while also combating opposing players who might go after his neck area.
Tuck seems resigned to the fact that he may have to play injured all season.
"I'd rather be healthy now," Tuck said Thursday. "But it's no guarantee if I sit out until the bye week that I will be healthy for the rest of the season. So you just have to go on how you are feeling on that day and that is why they call it day to day."
Jacobs and Baas have not practiced all week. Jacobs has a sprained medial collateral ligament, a source told ESPN NFL Insider Adam Schefter. A source told ESPNNewYork.com that the injury is considered "mild."
Baas has been battling a neck injury and was a spectator during stretching and offensive drills.
Asked if Baas would miss just a week, Coughlin replied, "I don't know. I hope so."
Baas' absence will end his personal streaks of 67 consecutive games played and 45 consecutive starts. He last missed a game on Sept. 10, 2007, when he did not suit up for the 49ers' season-opener against Arizona.
Kevin Boothe, who stepped in for Baas against Arizona, is expected to start against Seattle.
"Kevin's done well in there," Coughlin said. "We'd like to be able to think we're on course to stay basically the same."
Rookie cornerback Prince Amukamara, still recovering from foot surgery, did some running drills with a trainer on the farm field, but he also was ruled out for Sunday.
