Ryan was hurt in the third quarter of a 23-16 win over Suh's Detroit Lions.
"There are many, many, many plays that I could go back to that I watch on film all week that their offensive line has done," Suh said Monday, "and that they've been coached to do, as far as I know. It's not anything that's not been said; it's not anything that's new."
Fellow Lions defensive lineman Cliff Avril, also at the center of Atlanta's accusations, told the Lions' official website it is "mind-boggling" that the Lions were cast as a dirty team in comparison.
"You watch film of Atlanta's O-line and they're 20, 30 yards down the field cutting guys," Avril told the website. "You're running toward the pile and they're trying to clean you up. Everybody was protecting themselves. I guess since they couldn't clean us up in piles because guys were aware of it, they decide to make it like we're the dirty players."
Falcons players told the Atlanta Journal-Constitution after Sunday's game that Suh and Avril taunted Atlanta's Ryan while he was down.
Falcons receiver Roddy White told the Journal-Constitution that Avril was "kicking at [Ryan's] feet" while we writhed on the ground in pain. Center Todd McClure said Suh was taunting Ryan and calling for the Falcons to "get the cart."
"Basically, my whole thing is, with all the statements, they're going to say what they want to say -- he said, she said,'' Suh said. "I know, for the fact of the matter, Cliff, or anybody for that matter, would have kicked their quarterback, I'm sure there would have been a riot -- there would've been a fight broken out real quick. Because I guarantee you if that would've happened to [Lions quarterback] Matt Stafford, and he was on the ground and somebody kicked him, I guarantee you all hell would've broken loose."
Ryan tweaked a knee when offensive lineman Will Svitek stepped on his left ankle, but he came back in the game a short while later. He had an MRI on Monday and a team source texted to ESPN NFL Insider Adam Schefter, "All good. No damage to knee or ankle. Precautionary work." The source said the Falcons don't expect Ryan to miss any time.
Suh said: "To me it's karma for all the bad stuff they've done in the past. Their offensive lineman hurt their own quarterback."
Asked specifically if he said anything to Ryan after the injury, Suh said, "I have nothing to say. The man's sitting on the ground. We've obviously continued to do our job, getting to him, causing havoc. ... At that time, when he's on the ground, there's nothing that I have to say to him. We've done our job, we've been in his face, we've caused him to go down, we've caused his offensive lineman to hurt him."
Lions receiver Maurice Stovall told the Detroit Free Press that pregame tensions between the teams might have led to in-game hostility. Stovall said some Falcons players interrupted Detroit's pregame huddle when they came out of the tunnel.
"But the Falcons came up and kind of like got into our area. They got into a gray area, and we thought it was disrespectful," Stovall told the newspaper. "Naturally, when you're on your home field, you're not going to let someone just come in and walk through your huddle.
"So we had a few words with them. No punches were thrown. It was just a bunch of trash-talking, kind of like an intimidation type of thing. We were going back and forth with them. It's no harm done."
Not many Falcons were available Monday following their victory, but defensive lineman Corey Peters addressed the incident.
"I don't know. I wasn't out there. I believe our guys and what they said. I think that's uncalled for, personally," Peters said. "I would never do that. To see somebody on the ground injured, it could be seriously injured, you don't know at the time. ... I don't know what was said. I don't really want to get into it unless I know for sure what he said, but if he said it, it was uncalled for."
Atlanta coach Mike Smith downplayed the controversy.
"There's a lot of things said between the sidelines and know this: That was a physical, tough football game between two, I think very aggressive, teams -- probably the most physical game that we've played to this point," Smith said.
This is the second straight week the Lions are involved in a contentious aftermath to a game. Detroit's Jim Schwartz had to be separated from San Francisco's Jim Harbaugh the previous weekend after the two coaches were involved in an emotionally charged postgame handshake.
Suh concluded his remarks Monday with a dismissive shot at one of the players who criticized him.
"Do I need Rodney (sic) White's respect? No," Suh said. "Leave it at that."
