For the second straight day, the Giants said the 29-year-old Umenyiora did not practice because the player said one of his knees hurt.
Umenyiora did not report for the opening day of training camp a week ago Friday because he said general manager Jerry Reese had promised to renegotiate his contract. The deal has two years remaining and will pay the nine-year veteran $7.1 million. He came to camp the next day but has yet to practice.
The team gave Umenyiora's agent, Tony Agnone, permission to seek a trade earlier this week, but Reese abruptly rescinded that on Wednesday.
"It is a concern but we are day to day until we see how that is," Coughlin said.
