Burfict was fined a total of $69,454 for three separate plays -- roughing the passer, facemask and unnecessary roughness.
Burfict is appealing the fines.
Attar had said Wednesday that Burfict would not be fined for his controversial hit on Roethlisberger.
It appeared to many that Burfict dove for Roethlisberger's ankles after Roethlisberger released a pass during the first half of the Steelers' 33-20 win Sunday in Cincinnati. Burfict said he was pushed into Roethlisberger while he was attempting a pass rush.
"I don't buy he was pushed," Roethlisberger said during an appearance on Pittsburgh's 93.7 The Fan on Tuesday. "I think he was definitely diving low for my legs."
Asked to comment on Roethlisberger's claim, Burfict told ESPN on Wednesday: "It's football."
Burfict has a history of serious disciplinary issues for his play on the field. He previously was fined a total of $77,000 for four incidents, including a $25,000 fine last season for deliberately twisting the ankles of Panthers quarterback Cam Newton and tight end Greg Olsen.
