NFL Commissioner Roger Goodell today announced Lions DE Ndamukong Suh has been fined $20,000 for poking Patriots QB Tom Brady on Facebook earlier this week. It represents the league’s latest effort to curb Suh’s beastly intimidation tactics but is the first time he’s been fined by the league for something done off the field.

“Our players are prohibited from using overly aggressive tactics, be it on or off the field,” said Goodell. “Ndamuknog needs to know this type of behavior will not be allowed.”

Suh was quick to defend himself, saying he approaches social networking the same way he approaches football.

“If I’m on Facebook, I’m going all out,” said Suh. “It wasn’t my intention to intimidate Tom by reminding him of my presence online, but if he was intimidated by that, so be it. I’m not going to change the way I Facebook.”
