Giants CB Terrell Thomas injured his right knee in Sunday’s practice and underwent tests Monday after the knee swelled up.
An MRI revealed an injury to the right knee "involving the ACL," the team announced.
"I don’t know where they’re at, I haven’t heard the results. But the fact he came in this morning with a (swollen knee)..." said head coach Tom Coughlin, according to the New Jersey Star Ledger. "He walked up to me after practice (on Sunday) and thought he felt good. He didn’t really seem to have any issues and this morning when he came back in it was swollen."
Thomas missed the entire 2011 season after tearing the ACL in his right knee in a preseason game against the Bears. He signed a four-year deal to stay with the Giants this past spring.
"I don’t like the fact it’s swollen," Coughlin added, reportedly sounding pessimistic, "but I’m not a doctor. Don’t go basing it on me."
In 2010, Thomas played in all 16 games and made 101 tackles, 21 passes defensed and five interceptions.
