Receiver Dez Bryant missed another day of practice. His right ankle, which he injured in training camp, is sore again.
"I am worried that he might not be able to play," Cowboys coach Wade Phillips said. "...It’s been on and off. Those high-ankle sprains tend to last for a while and sometimes don’t get completely well."
Starting center Andre Gurode also might join Bryant on the sideline Sunday. He injured his knee on an interception at the end of the 34-27 loss to the Titans but did not have trouble with it until practice Thursday. The Cowboys sent him for an MRI.
"That's a concern, obviously," Phillips said.
Starting left guard Kyle Kosier would start at center if Gurode is unable to play. Kosier had never played center until the Cowboys cut backup center/guard Cory Procter during the off-season. Undrafted rookie free agent Phil Costa would be active to serve as Kosier's backup. Montrae Holland would start at left guard.
Bryant has had a series of nagging injuries so far in his young career. He also has a rib injury, though Phillips said Bryant's ribs were not a concern.
Bryant, the Cowboys' first-round draft pick, initially injured his ankle July 30 during training camp in San Antonio. He missed all of the preseason, playing his first game in the season opener against the Redskins. Bryant is the team's fourth leading receiver with 17 catches for 180 yards. He has returned a punt 62 yards for a touchdown.
"Anytime you're not practicing, it hurts, as far as young players knowing assignments and what to do," Phillips said. "Now, he’s worked hard in the classroom, and I think that’s helped him. He’s still practiced quite a bit. That’s also helped. We’ve also had walk-throughs and things like that that we do with the players that he’s been able to participate in."
The Cowboys could activate receiver Jesse Holley off the practice squad for Sunday's game. Holley has been practicing with the first team special teams.
Safety Alan Ball (shoulder), linebacker Bradie James (knee), defensive end Igor Olshansky (knee) and tight end Martellus Bennett (ankle) were limited in practice.
