Williams, whom the Oakland Raiders drafted in the third round from Fresno State last season, missed all but one game with a knee injury a year ago. Williams' latest injury is excepted to cause him to miss six weeks.
"He was having a good camp," Raiders head coach Norv Turner said. "I think he's going to be a heck of a player."
Williams injured his shoulder on a punt return in Saturday's 33-30 win over the San Francisco 49ers.
Playing time for Dallas
The starters will likely receive a little more playing time for Saturday‘s home game against the Dallas Cowboys. Rich Gannon, Kerry Collins and Marques Tuiasosopo will likely play about 1 ½ quarters and Turner is hopeful of getting No. 4 man Tee Martin some playing time.
All three quarterbacks shined in the win over San Francisco along with other positions. Then again, there were plenty of aspects that need attention -- like 21 penalties and several missed tackles.
"Between the first and second exhibition you get a chance to clean up a lot of things," Turner said. "We have to eliminate the penalties and we have to tackle better. Dallas presents some real problems. They were one of the best defensive teams last year."
New number for Gallery
Oakland Raiders offensive tackle Robert Gallery sported a new look (well, sort of) -- and a new number. Gallery, whom Oakland selected with the top overall pick in the draft from the University of Iowa, had been wearing No. 74 but has since switched to No. 76.
Gallery's beyond shoulder length hair is still present despite several rookies getting the barber treatment Wednesday. Instead Gallery had splotches of his beard shaved along with parts of his eyebrows. Gallery has since shaved his beard entirely.
The first number, 74, perhaps represented a curse. Matt Stinchcomb, now a Tampa Bay Buccaneer, was drafted by Oakland with the No. 18 pick in the 1998 draft. Stinchcomb, however, was plagued by injuries throughout his Raider career. Gallery, incidentally, hyper extended his elbow in Monday's practice.
The injury is not believed to be serious but his status for Saturday is still up in the air along with that of fellow rookie Carlos Francis, a wide receiver from Texas Tech. Francis hurt his hamstring. Running back Amos Zereoue (contusion) has been ruled out.
