Zack Bowman active vs. Dolphins

MIAMI GARDENS, Fla. -- Chicago Bears cornerback Zack Bowman is active for Thursday's night game against the Miami Dolphins for the first time since suffering a sprained right foot against the Seattle Seahawks on Oct. 17.

Although Bowman's foot may not be 100 percent, the cornerback is expected to play on special teams Thursday night. Tim Jennings, however, will continue to see the majority, if not all, of the snaps at left cornerback against Miami.

The Bears announced on Wednesday that linebacker Pisa Tinoisamoa will miss the game because of a knee injury, so Nick Roach gets the start at strong-side linebacker. Roach made 15 starts last season (12 at strong side, three at middle) and finished tied for the team lead with 10 tackles for a loss.

Tinoismoa's injury isn't believed to be serious, but it is the same knee he experienced problems with last season, according to Bears general manager Jerry Angelo.

"I think he should be fine," Angelo said. "He's had some medical issues that have been well-documented. He had something with his knee, but we feel he'll be fine. If we had the regular cycle of a week, he might have been able to play on Sunday. But being the short week, we didn't want to push it.

"It's manageable. We feel he's going to be fine. Everything will [be] up and going with him. He's really had a fine year for us."

As expected, defensive tackle Marcus Harrison is active for the second consecutive week.

Other Bears' inactives include: Caleb Hanie (third quarterback), Joshua Moore, Barry Turner, Corey Wootton, Desmond Clark, Kahlil Bell and Edwin Williams.
