Defensive tackle Jason Hatcher will not play against the Saints.
Executive vice president Stephen Jones said Hatcher is not available as the Cowboys get ready to play the Saints on Sunday night.
Hatcher left last week's game in the fourth quarter because of a stinger. He said it caused him to lose strength in his left arm. He practiced Friday and underwent acupuncture, muscle stimulation and massage until 9:30 that night in an effort to play.
Hatcher is the Cowboys' sack leader with seven.
