Williams, who was placed on the reserve/COVID-19 list Wednesday after being deemed a close contact of teammate Keenan Allen, has reportedly tested negative for the virus, according to Tyler Dragon of USA Today.
The report adds that the Chargers are optimistic Williams will be able to play Sunday versus the Giants. Per Ian Rapoport of NFL Network, Williams could be cleared by Saturday, based on his understanding that the high-risk close contact occurred Monday.
