It is not just the injury to his foot, incurred four days after he returned to full-contact practice, that has troubled Williams.

It was only a week ago that Williams, 32, was cleared to compete in full-contact practices.

Van Horn hopes to get involved in full-contact practices Saturday "at the latest."

Owens has still not participated in a full-contact practice, and there is some chance he will not play, Burkholder said.

"I have to wait a couple more days before I can go through a full-contact practice," Dvorak said.

"They put me in full-contact practice from day one," he said.

He said the true test was the first full-contact practice, not the first preseason game.

Booth was not cleared for full-contact practice with the team on January 25, 2010.

He is expected to begin full-contact practice within the next week.

Weatherspoon is no longer wearing an air cast and hopes to begin full-contact practices within the next week.
