Williams, 28, signed a four-year, $44 million with the Raiders last season, but missed 2 games due to plantar fasciitis, which slowed him en route to a down year in terms of production.
Earlier this month, Williams said the foot issue was behind him.
“I feel 100%,” Williams said at the time. “I’m excited. I feel fast, feel back to myself. So, glad to feel that way, finally kind of past that.”
