According to an Associated Press report, Oakland Raiders head coach Norv Turner said that Williams tore an anterior cruciate ligament, but was unsure which knee was injured. One would assume that the Raiders would likely place Williams on injured reserve. Williams was reportedly injured while making a block.
Injuries curtailing Williams' season is nothing new. The third-year man out of Fresno State has had injuries to his knee, shoulder and ankle that have allowed him to play in just nine games in his first two seasons.
Williams, however, showed some promise last season in the nine games he played, four in a starting assignment. Williams totaled 22 tackles and added three passes defended. Williams' injury further thins out a position most people consider the weak link of the Raiders roster and frees up playing time for Grant Irons and rookie Kirk Morrison.
