FRISCO, Texas -- Dallas Cowboys defensive end David Irving was fined $9,115 for unnecessary roughness for his disqualification Sunday against the Cleveland Browns, according to a source.

Irving was ejected for throwing a punch at Browns center Cameron Erving on the fifth play of the game. Erving was also ejected after ripping Irving's helmet off.

It is not known if Erving also was fined. Earlier this week, he called the incident with Irving "an unfortunate event."

"I acted how I feel I was supposed to react, but I have to know as a professional I can't grab a guy's helmet and throw it," Erving said.

Irving was upset at what he felt like was a blindside block from Erving as quarterback Cody Kessler scrambled. Irving said Erving would not allow him to get off the ground after they became entangled, which led to the quick tussle.

It could have been worse for Irving. The fine for fighting is $30,387. Irving makes $30,882 each week with his $525,000 base salary, however, according to the collective bargaining agreement a fine may be reduced if it exceeds 25 percent of one week of a player's salary for a first offense.

"They reached out to me," Irving said of receiving notice from the NFL. "And I definitely learned my lesson. It won't happen again. I can tell you that much."

Irving expressed concern about having to deal with an upset defensive coordinator Rod Marinelli after the game. Marinelli took a sarcastic approach.

"I just said you look really fresh this week," Marinelli said.
