Suh was fined $100,000 for an illegal block on a Minnesota Vikings player in the Detroit Lions' season-opening win last weekend. It is believed to be the NFL's biggest monetary fine for on-field conduct, not including the dollars lost by players due to suspensions.
"It's going through the appeals process," Suh said Wednesday.
Suh's agent, Roosevelt Barnes, said he expects the appeal to be heard later this week, when he hopes to provide another perspective to reduce his client's fine.
"Everyone is talking about how Ndamukong shouldn't have blocked the 300-pound lineman because there was no way he was going to catch a linebacker," Barnes said in a telephone interview with The Associated Press. "If that's the case, the lineman should've known he wasn't going to catch the linebacker. But the lineman did attempt to catch the linebacker and Ndamukong attempted to block him. But everyone wants to make Ndamukong out to be a villain."
Suh vowed that he's not going to change his ways on the field, including when Detroit (1-0) goes on the road to play the Arizona Cardinals (0-1) on Sunday.
