Umenyiora was not on the practice field with the Giants on Monday morning. After practice, coach Tom Coughlin was asked whether Umenyiora would play on Sunday, and he responded, "I don't think so. A little early."
The two-time Pro Bowler sat out the beginning of Giants training camp because he was dissatisfied with his current contract. Soon after he began practicing, his right knee started bothering him. He had arthroscopic surgery on the knee on Aug. 19. But as late as last Friday, Coughlin sounded like he was holding out hope that Umenyiora would be available for Week 1.
The only other member of the Giants' 53-man roster not on the field on Monday was the team's first-round draft pick, Prince Amukamara, who suffered a broken left foot in training camp in just his second practice with the team. Amukamara had surgery and is likely out several weeks.
Defensive end Justin Tuck was on the field and in uniform, but he also did not practice on Monday. Tuck suffered a burner in the team's third preseason game versus the New York Jets on Aug. 29, but Coughlin expects him to play on Sunday.
"He's well on his way, feels good," Coughlin said. "Wednesday will be a better day for him [to practice]."
