OXNARD, Calif. -- The Cowboys will have their tenth practice of training camp Friday.

Jay Ratliff to practice more: The starting nose tackle has gotten work in walkthroughs but not full practices until Thursday afternoon. He got a handful of snaps with the first team before talking to the trainers about his balky foot. Team owner/general manager Jerry Jones said Ratliff got a handful of snaps as a precaution but might get more Friday. Ratliff won't play at Oakland. If his foot feels better, he might go against San Diego in the second preseason game.

Interior line play getting better: Guard Mackenzy Bernadeau looked pretty good in his full practice debut Thursday. There is a question about using him at Oakland on Monday night. It's doubtful the Cowboys plan on using him, but it was good to see him attack defensive players. The test is how he performs today, in his first back-to-back practices.

Who returns kicks?: The Cowboys have used multiple players on kick and punt returns, including Dez Bryant, Dwayne Harris and Felix Jones among others. Last year's kicking game was weak, as evident by its 23.3 kick return average and 7.1 punt return average. The Cowboys need to find playmakers and it's a strong indication they want to use some of their more elusive players in Bryant and Jones.

The schedule for Friday: Jason Garrett speaks with reporters at 2 p.m. CT and practice starts at 4:30 p.m. CT. The Cowboys will practice Friday and Saturday and then have a walkthrough Sunday before traveling to Oakland for the first preseason game. If you attend practice, expect some preparations for the Raiders game to take place.
