Injury wire: Bowman, Manningham practice

SANTA CLARA, Calif. -- The San Francisco 49ers' injury report looked better Thursday than it did Wednesday.

Standout linebacker NaVorro Bowman (knee, shoulder) and pivotal receiver Mario Manningham (knee) both practiced on a limited basis Thursday, after both sat out Wednesday. Barring setbacks, expect both players to play Sunday against St. Louis.

Defensive tackle Ray McDonald (ankle) continued to be out of practice. He hasn't played the past two games and his chances of playing Sunday may be dwindling.

Meanwhile, receiver Michael Crabtree continued to practice fully and he's on track to play some Sunday. Crabtree, who tore his Achilles in May, will be eased back into action as he makes his season debut.

Rookie receiver Quinton Patton continued to be limited Thursday as he recovers from a broken foot he suffered in Week 4. He returned to practice Wednesday.
