Harrison also said that he doesn't expect to hear from the league.
"I don't think it's suspension-worthy," Harrison said of the hit that drew a 15-yard penalty. "I don't think it's worthy of anything, but that's just my own personal thoughts."
Harrison added that referee Ed Hochuli "didn't even call it helmet-to- helmet. He called it roughing the passer."
Harrison was asked if McCoy ducked into the hit.
"Well he took off running with it and at the last second he chucked and ducked," Harrison said.
Harrison was fined last year for similar hits on Mohamed Massaquoi ($75,000), Ryan Fitzpatrick ($25,000), Drew Brees ($20,000) and Vince Young ($5,000) for a total of $125,000. The fine for the hit on Massaquoi was later reduced to $50,000.
Harrison's history with hits involving his helmet has led to speculation that he would be suspended for a game, even two, by the NFL this week.
Harrison was asked if he'd be "honked off" if the league does suspend him.
"I'm not going to go with ifs," he said. "I don't have to worry about that. We'll see what happens when the time comes and I'll give you what I got then."
Teammates were mum on the topic. When asked for his opinion on the matter, Larry Foote pointed to his coach, Mike Tomlin, as he walked past the interview.
"My opinion is whatever this guy's opinion is. Isn't that right, coach?" said Foote.
"That's why we brought you back," Tomlin said as he shook hands with Foote. "You're a wise man. Too bad it took me, what, five years to realize it."
Tomlin had earlier told Harrison's teammates not to comment on the matter.
