Cameron Heyward was the latest victim of the No Fun League.

The former Ohio State defensive lineman honored his late father, Craig, who died of brain cancer, on Monday Night Football. Heyward wore eye black that read “Iron Head,” which was a tribute to his father’s nickname.

The NFL was not a fan of Heyward’s custom eye black.

Craig Heyward was a former All-American at Pittsburgh, and he played 11 seasons in the NFL. He died in 2006 at age 39, but his son wanted to honor him on the big stage on Monday.

The NFL didn’t make an exception to honor one of its former veterans. Instead, it handed Heyward a hefty fine.

Sooner or later, the NFL will stop worrying so much about its ever-profitable bottom line and make some exceptions to its air-tight rules.
