The Niners got bad injury news today, as they learned that corner Shawntae Spencer will miss the rest of 08 with a torn ligament in his left knee. The fifth-year pro will be placed on IR after he undergoes surgery on Wednesday to fix the ligament. Spencer hurt the knee late in the game vs the Seahawks two weeks ago, and missed last week’s home win vs the Lions. Last season Spencer played in 11 games, making 28 total tackles. He has played in 57 career games, making 244 tackles with six interceptions.
