EAST RUTHERFORD, N.J. -- Justin Tuck missed a second straight day of practice due to stiffness in his back.
"Today was not what we wanted," coach Tom Coughlin said Thursday about Tuck. "He's not quite as nifty and nimble as we hoped. We will have to see [about Saturday's preseason opener]. I actually thought he would work today."
Tuck said before missing practice that he believes the issue isn't serious and hopes he will be healthy by next week. He isn't sure if he will play Saturday in Pittsburgh.
"I feel better than I did yesterday," Tuck said before practice. "I know exactly what it stemmed from ... but it is nothing serious. Just a little tightness."
"I've played in worst pain, I can tell you that," he added. "Just want to be smart and make sure it is nothing that will linger."
Tuck has worked hard this offseason to get in terrific shape. He wants to make sure that nothing will nag him this season, like some injuries have in the past.
"I don't think this is something that is going to be much more of an issue after this week," Tuck said.
Coughlin said right guard Chris Snee and cornerback Terrell Thomas will not play against Pittsburgh. Both veterans just came off the physically unable to perform list earlier this week and are being eased back into the flow.
"They don't have enough practice time," Coughlin said.
Offensive lineman Justin Pugh (concussion) also likely is out. Coughlin expects the first-round pick to be cleared for practice next week.
Coughlin wasn't sure if Hakeem Nicks will see snaps in the preseason opener. Nicks has been practicing this week, but the team is taking a cautious approach with its star receiver to make sure he enters the season at full strength.
