Bryant, who missed practice on Thursday and Friday, is listed as questionable on the injury report.
He continues to get treatment for the injury suffered while returning a punt in Week 1 against the New York Jets.
Bryant has undergone extensive treatment to keep the swelling down so the leg can loosen up.
Bryant was the last player on the practice field on Friday because he was getting treatment for his leg.
"We'll see," said Bryant when asked if he would play Sunday.
Bryant missed the Cowboys' Week 2 game at San Francisco with the thigh injury. He tried to warm up before the game, but the leg didn't get loose.
He did play in the team's Monday night game against the Washington Redskins and caught four passes for 63 yards. Bryant did not return punts.
If Bryant is unable to play, Kevin Ogletree and Jesse Holley become the primary receivers. Laurent Robinson and rookie Dwayne Harris are the other receivers. Harris has not caught a pass in an NFL game.
Dallas' other starting receiver, Miles Austin, will not play with a hamstring injury.
