Ware, who is playing with a stress fracture in his foot, was a full participant in practice this week. But despite practicing, Ware was listed on the injury report Friday with the new injury.
Ware, who leads the team with 32 quarterback pressures and eight sacks, does wear a wrist brace during some games and practices.
Having a injury to his wrist causes problems. Ware uses his hands to push off offensive linemen and tight ends. Last week, Oakland sent a tight end and, sometimes, a guard his way to slow his progress toward the quarterback.
Ware said he's getting extra attention this year as a result of him leading the NFL with 20 sacks last year. In October, he signed a six-year, $78 million contract extension.
Ware also has played most of the season with a foot problem that he recently said was getting better.
