The NFL imposed several fines following the Week 5 games, with Maxx Crosby, the defensive end for the Las Vegas Raiders, receiving the largest fine of $23,882 for unnecessary roughness. This penalty was issued due to illegal use of his helmet during the Raiders' 45-17 loss against the New England Patriots. The incident occurred during the first quarter when Crosby committed a foul after a Drake Maye touchdown pass.

Other notable fines included:

• James Cook, running back for the Buffalo Bills, was fined $21,167 for helmet use against the Los Angeles Rams, despite not being flagged for the infraction.

• Bradley Chubb of the Bills faced a fine for taunting following a postgame exchange with Alaric Jackson of the Rams, which escalated to a strike from Jackson, resulting in a suspension.

• Minkah Fitzpatrick, safety for the New York Jets, was fined $17,911 for a hit that sidelined KC Concepcion, wide receiver for the Cleveland Browns. Fitzpatrick maintained the hit was not dirty and also received a separate fine of $11,941 for a facemask.

Additionally, a fight during the previous week's London game led to fines for Jeremiah Trotter of the Philadelphia Eagles and Bryan Thomas Jr. of the Jacksonville Jaguars due to their involvement in the altercation.

These disciplinary actions highlight the league's ongoing efforts to maintain player safety and sportsmanship.
