Chargers WR Mike Williams' "close contact" with COVID-positive Keenan Allen came on Monday, So Williams could be cleared to return to the team on Saturday and play against the Giants on Sunday. (source)
Williams has had a topsy-turvy season. He's averaged 12.5 fantasy points per game (0.5 PPR) since Week 11, and he had five catches for 110 yards last week against the Bengals – his first 100-yard day since Week 5. Williams will be a low-end WR2 if he plays, and he becomes a must-start in fantasy if he plays but Keenan Allen doesn't.
