The New York Giants’ cornerback, who missed last season with a torn anterior cruciate ligament, re-injured his ACL in training camp Sunday afternoon. On Monday, an MRI showed that, while the ACL is not completely torn, a tear is “still there,” according to the Newark Star-Ledger.

“No decision has been made at this point,” Ronnie Barnes, the Giants’ vice president of medical services, said in a statement issued by the Giants. “Terrell is going to consult with [Dr. Arthur] Ting, who performed an allograft reconstruction of the ACL in September.”

Thomas, who is expected to have an arthroscopic procedure to determine the extent of the damage, appears to have suffered the latest injury when he slipped while covering Domenik Hixon in passing drills.

“He walked up to me after practice [on Sunday] and thought he felt good,” Coach Tom Coughlin said. “He didn’t really seem to have any issues and this morning when he came back in, it was swollen.”

Thomas first tore his ACL when he was playing at USC in 2005. In a preseason game last on Aug. 22, he tore the ligament again in a collision with Jason Pierre-Paul. He missed the first practice of camp Friday because of a stiff lower back and, on Saturday, gave fans “T2” shirts for keeping him involved during the Giants’ run to the Super Bowl.

“They always kept me a part of it, regardless of win or loss. ‘T.T., we need you out there, you’re never forgotten. You’re a part of the team,’” he said.

Thomas, 27, played in every game in 2009 and 2010, leading the team in interceptions (five, each season) and tackles. He signed a four-year contract extension in March.
