Ratliff is returning from Atlanta on Monday but isn't expected to participate in the Cowboys' voluntary OTA workouts this week. The three-day mandatory minicamp begins Friday.
Ratliff's contract played no role in his absence from the team's Valley Ranch practice facility, according to the source.
Ratliff signed a five-year, $20.5 million contract in December 2007, months after the former seventh-round pick replaced injured Jason Ferguson as the Cowboys' starting nose tackle. Ratliff has since earned a pair of trips to the Pro Bowl. He's a rarity as a 3-4 nose tackle who plays almost every defensive snap. His 13.5 sacks the last two seasons rank second behind All-Pro outside linebacker DeMarcus Ware among the Cowboys.
