In 2008, Favre finished the year with an undisclosed arm injury (a partially torn biceps tendon). Favre fully participated in every practice (without any Sherman-style “general rest days”), Favre played in every game, and no one would have known anything about it unless and until Favre decided as part of his arrival in Minnesota to explain his sputtering performances down the stretch in 2008 by talking repeatedly about an arm injury that hadn’t been disclosed.
Did the Jets get a warning? Nope. The
NFL fined the team $75,000, it separately fined then-G.M. Mike Tannenbaum $25,000, and it also fined former coach Eric Mangini $25,000.
