Despite the messy way his Packers career ended, Brett Favre remains one of the most iconic figures in recent NFL history. So his words on football-related matters carry plenty of weight, especially when he discusses the toll playing the sport took on him.

Favre made an appearance to promote a company called Prevacus, which is working on a drug that promises to reduce the after-effects of concussions. In a report by Mississippi television station WDAM, Favre made these comments regarding whether he’d let his son play football:

“It’s a violent sport, you know, and for two reasons, I don’t know if I would let him play. The pressures to live up to what your dad had done, but more importantly, the damage that is done by playing.”

The comments built on ones he made about his son on “Today” in November 2013, when Favre said he would be “real leery of him playing.” In that interview, Favre told Matt Lauer that “I’ve talked to several doctors, asking them about symptoms, and one of them is not being able to finish a sentence, or not remembering a word — a specific word. I’ve noticed lately, if there’s any symptom at all, that one being the one that shows the most.’’

In Monday’s appearance, Favre said that “the cumulative effect [of concussions] is yet to be known, but it’s probably not great, not good.”

Prevacus added Favre to its Sports Advisory Board, so he has a direct interest in promoting its product, but there is also little doubt the future Hall of Famer is legitimately troubled by what playing football has done to him, and what it might do to his children.
