Chris Canty's return to Dallas will have to wait.
The New York Giants defensive lineman missed practice Thursday with a calf injury, and a league source told NFL Network's Jason La Canfora that Canty will not play in Sunday night's game against the Cowboys.
Canty, who left the Cowboys to sign with the Giants as a free agent this offseason, was hurt in practice Wednesday and will miss a game for the first time in his five-year NFL career. He received treatment Thursday while the Giants practiced.
Giants starting safety Kenny Phillips (knee) returned to practice on a limited basis Thursday and had a couple of interceptions. Michael Johnson, the other starting safety, missed his second practice with a shoulder injury, but coach Tom Coughlin believes the third-year pro has a chance to play. Linebacker Michael Boley (hip) showed improvement and has a shot at playing, according to Coughlin.
