Williams tackled Decker well out of bounds in the fourth quarter and was penalized for unnecessary roughness, his sixth penalty of the season to rank fourth on the team.
Normally, players are notified by Thursday whether they've been punished by the NFL.
"Nope," Williams said when asked if he had been fined. "I knew I was close to the sideline. I wanted to get him out of bounds and I didn't know what he was trying to do."
Decker caught eight passes for 133 yards, including a 51-yard touchdown where he ran past Williams and free safety Ed Reed with a stutter-step double-move pattern.
"He was all right," Williams said. "I think they had a good game plan for him. He got his separation and had a bunch of double moves."
Cruz leads the Giants with 79 receptions for 1,019 yards and nine touchdowns. Nicks has 53 catches for 692 yards and three touchdowns.
"Another talented group, we've been facing talented groups all season," Williams said. "It's another battle. We've got to step up to the plate."
