Detroit Lions defensive tackle Ndamukong Suh has reportedly asked his representatives to look into appealing against his record fine.
Suh was slapped with a $100,000 (£63,600) fine for a low block on Minnesota Vikings centre John Sullivan during Sunday's match between the two sides, the largest fine in NFL history without a suspension involving the loss of game checks.
The 26-year-old is believed to be preparing an appeal on the grounds that his punishment is excessive, according to league sources.
Suh was fined $30,000 last season for kicking Houston Texans quarterback Matt Schaub, while he has also been handed smaller fines for roughing up quarterbacks Andy Dalton, Jay Cutler and Jake Delhomme.
The former first-round draft pick was penalised on the field with a 15-yard penalty, although his play also caused the officials to rule out an interception touchdown.
