Commissioner Roger Goodell notified Adams of the fine Monday. League spokesman Greg Aiello said it is for conduct detrimental to the NFL. Adams was seen making the gesture while in his luxury suite and again on the field after Sunday’s 41-17 victory.
The NFL fined former 49ers owner Eddie DeBartolo $1 million after he pleaded guilty to a felony and suspended him for the 1999 season.
Since then, the biggest fine handed down by the NFL to an individual was $500,000 to New England Patriots coach Bill Belichick for the Spygate scandal. The league also fined the New York Jets and former coach Eric Mangini $125,000 in September for violating its rules on injury reporting with Brett Favre last season.
