SANTA CLARA -- Mario Williams' left wrist is ailing, but the 49ers still are heaping respect on the Buffalo Bills' high-priced defensive end.
"He doesn't want excuses. He's a grown man," said right tackle Anthony Davis, who will match up against Williams on Sunday when the Bills (2-2) visit the 49ers (3-1).
One the NFL's biggest offseason moves saw Williams ditch the AFC favorite Houston Texans for the money-throwing Bills. He received the most guaranteed money ever for a defensive player, $50 million, as part of a six-year, $100 million deal.
So far, Williams has only 11/2 sacks, and he told Buffalo reporters Wednesday that he's frustrated with a wrist injury that's lingered since the exhibition finale.
"I'm a hands-on player, and it's all about power in my game," Williams said. "It's been odd having a little nick and not using it to the full extent."
Williams still is commanding multiple blockers, and offenses are moving the ball away from him, according to 49ers offensive coordinator Greg Roman, who added that he "didn't notice anything wrong" with Williams' wrist.
Williams has not appeared on the Bills' injury report all season, and coach Chan Gailey made no mention of Williams' wrist in Wednesday's conference call with Bay Area media. "He has ended up drawing two and three blockers quite a bit, so his statistics are not where they need to be," Gailey said.
Williams tallied two tackles and no sacks in Sunday's 52-28 loss to the New England Patriots, who shredded the Bills defense for 45 second-half points.
Running back Anthony Dixon's brother, Rashun, just completed his fifth season as a Single-A outfielder in the A's farm system, splitting time this year between the Stockton Ports and Burlington (Iowa) Bees. "I can't say I'm on the bandwagon fully," Dixon said. "But there's a little bit in me."
