There's been no shortage of bad blood between the Green Bay Packers and Detroit Lions' linemen since Ndamukong Suh first stomped Evan Dietrich-Smith three years ago.
Before last year's Thanksgiving matchup, Josh Sitton called the Lions "a bunch of dirtbags." Four unsportsmanlike and unnecessary roughness penalties were called in the game, though neither Sitton nor Suh were involved.
After racking up more than $200,000 in fines his first four NFL seasons, Suh seems to have toned down his antics since Jim Caldwell replaced Jim Schwartz.
Still, it remains to be seen if the combustible elements will erupt again this Sunday.
"You never really go into a game trying to press anybody's buttons and try to get them to throw a punch," right guard T.J. Lang said. "But the one thing you do is you try to play hard and as physical as you can and finish every play, and if something happens extracurricular, you know you let it take care of itself.
"He's had his issues in the past, but it's not something that you've really seen lately with him playing football, so in my mind it's an issue that he's made a lot of work to correct."
Lang, Sitton and tackle David Bakhtiari mixed it up in Sunday's 31-24 win over the New York Jets following Randall Cobb's successful two-point conversion, though New York defensive lineman Sheldon Richardson and Muhammad Wilkerson were seen as the instigators.
Richardson told ESPN.com Thursday he was fined for the altercation. Meanwhile, Wilkerson will be automatically fined for his ejection after throwing a punch during the scuffle.
The Packers aren't looking for a fight, but they've made it known they aren't backing down, either.
"You never want to back down from anything," Lang said. "If something happens, I mean, our first two games now we've had a couple little scuffles, so that's not us trying to be guys like that trying to cause things. You always protect yourself and protect your teammates if it gets to a point like that."
-- Either the Packers truly don't know who was to blame for the sideline penalty they took in the second quarter against the Jets or they simply aren't telling.
Whatever the case, the Packers spent a portion of their team meetings discussing sideline awareness and boundary management after the team picked up a 15-yard unsportsmanlike flag when the sideline felt receiver Jordy Nelson was hit late by Jets defensive lineman Sheldon Richardson.
"We don't know who was actually penalized," Packers coach Mike McCarthy said. "Based on the communication with the official during, after the event and even right before halftime, and who he determined it was on and looking at the video and things like that. It's obviously something happened, but we talked about it again today."
-- Inside linebacker Brad Jones (quad) and outside linebacker Andy Mulumba (torn ACL) didn't practice Thursday. It's expected Mulumba will be placed on injured reserve before Sunday's game against Detroit.
-- Defensive back Micah Hyde was a full participant Thursday after the knee injury he suffered against the Jets limited him Wednesday. Tackle Bryan Bulaga (MCL sprain) still was limited, but seems to be moving around better.
