During last November's 37-13 home victory over the Lions, Moore was ejected after retaliating on a play that precipitated a melee.
Earlier in that game, Lions defensive tackle Ndamukong Suh had ripped off the helmet of Bears quarterback Jay Cutler with no penalty called. And defensive lineman Nick Fairley, who was penalized for roughing the quarterback in the third quarter, later was fined $15,000 for the late hit and driving Cutler into the ground unnecessarily.
Moore hopes Monday night's game will not deteriorate into a series of dirty plays.
"I don't think it's bad blood. I just think a guy (Stafford) was frustrated," Moore said Wednesday at Halas Hall. "He did something; I did something. That was pretty much it. I don't really think of it as something that keeps going or whatever. But if it happens again, I wouldn't react differently than I did."
Moore was fined $15,000 and Stafford $7,500 for "grabbing an opponent by the helmet opening."
The Lions have been known to push the envelope, or play to the echo of the whistle to evoke a response from the opposition.
"It's hard sometimes. You just feel as a man sometimes that when a guy hits you, you just want to go back at him," Moore said. "You have to know you can't do it. It depends sometimes on how the game is going. If we're up by a lot, then the shots get real dirty sometimes. If the game's close, they know it and we know it that you can't really do anything to hurt your team."
The Lions (2-3) are coming off a comeback victory on the road against the Eagles and hope to re-enter the NFC North title chase.
"Previously, they weren't good. It's not really a rivalry until you really get good," Moore said. "They are a better team now, so it's more of a rivalry. If we win, we kind of knock them down. If they win, they will be 3-3 and feeling like they are pretty much still in it. I feel we can take all of the confidence they have."
