The Philadelphia Eagles will be without defensive tackle Fletcher Cox on Sunday against the Arizona Cardinals as head coach Doug Pederson has already ruled him out. Cox, who is currently battling a lingering calf injury, will now miss his second straight game.

“He’s progressing nicely,” Pederson said, per the team site. “He’s right on track where he needs to be.”

Cox, 26, was injured during the Eagles’ Week 3 win over the rival New York Giants. He posted a sack in each of the first two games of the season and also forced a fumble in Week 1 against the Washington Redskins. The defensive tackle and Mississippi State product earned himself a six-year contract extension worth $103 million last summer and responded by being named to the Pro Bowl last season for the second consecutive year. Philadelphia’s defense, along with six other NFL clubs, has recorded 10 total sacks on the season. Cox, who has been in the league since 2012, has 30.5 sacks of his own during his career.
