Simon, who took a physical with the Titans a week ago, was expected to be at practice later today.

"Corey brings a combination of run-stuffing size and pass-rushing ability to the defensive tackle position," general manager Mike Reinfeldt said in a statement. "Prior to last season, he has been a consistent and productive player who contributed to playoff teams and we are excited to see him get a second chance here with the Titans to prove he still has that ability."

Indianapolis released Simon on Aug. 4 after he failed his physical with the Colts at the start of training camp. He had arthroscopic knee surgery but was placed on the non-football illness-injury list Oct. 5 with an undisclosed ailment a year after signing a five-year, $30 million contract.

He was the sixth pick overall in 2000 by the Philadelphia Eagles and a Pro Bowler in 2003. He spent five seasons with Philadelphia and had 270 tackles and 32 sacks, but the Eagles released him just before the 2005 season because he refused to sign a one-year franchise tender.
