Lonnie Johnson Jr. isn’t making any friends in Green Bay.

On Monday, the first day of joint practices between the Texans and Packers, the rookie cornerback was kicked off the field after leveling two Packers players during a non-tackling session.

Johnson, whom the Texans selected in the second round, drilled rookie tight end Jace Sternberger, whose helmet came flying off. Johnson stood over him and flexed, causing multiple Packers players to come over and confront him.

It wasn’t until another hit, however, on receiver Trevor Davis on a kickoff return that Texans coach Bill O’Brien was prompted to send Johnson to the showers.

“It was a play that developed over there, and it was time for Lonnie to head to the showers,” O’Brien told reporters.

O’Brien added that it was “not a big deal.” The Packers struck a different tune.

“That was unnecessary,” Packers receiver Davante Adams said. “You’ve got plenty of time for that. You can do it in the game and you get fined. Be a coward when you do stuff like that in practice, it’s not a good look. We take care of each other up here. I don’t know how they practice, I don’t know what they do over there, but there’s consequences for stuff like that…

“It’s a brotherhood across the league, period. I had plenty of times where I could take somebody out, but I decided not to because I felt like that’s not the appropriate thing to do when we’re trying to get better and look out for one another.”

Johnson posted a picture of himself flexing over Sternberger on Instagram, captioning it, “Gotta drop on this flexing… #itsfootball.” Sternberger returned to practice after he was evaluated for a concussion, but Davis did not return from his Johnson-issued hit.

“I respect a lot of those guys over there on the Texans. I’ve played against them quite a bit over my career,” Packers tight end Jimmy Graham said. “Obviously he’s a rookie, and he needs to know you can’t be hitting guys live in practice. That’s absolutely ridiculous. And we’re not going to stand for that here, obviously.

“I know his older guys over there are going to be on him about it because my young guy’s just running through a zone, obviously. Just run by him. We know you’re going to blow him up in a game. This isn’t a game. We’re going to play on Thursday. You can do that then. It’s one of those things, rookie on rookie, but [No.] 32 has to chill out.”

Joint practices often get chippy, with players grumpy after practicing every day against the same guys looking to hit new players. Packers coach Matt LaFleur instructed his team to avoid that type of behavior – a talk that seemed to be missing on the Houston sidelines.

“I thought there was no place for that,” LaFleur said. “We addressed it. It’s an unfortunate deal, because I was pretty clear with out guys we’re not doing that stuff.”

Packers right guard Billy Turner echoed LaFleur’s instructions, and also claimed the Packers were clear in their intentions to protect their players if the Texans started taking shots. They’re not looking to start any fights on Day 2, but won’t hesitate to confront any dirty plays.

“I’m not going to say I expect it, but, again, I’m going to protect my teammates at any cost,” Turner said.
