The Houston Texans and Green Bay Packers held a joint practice on Monday, and it didn’t end particularly well.

During the session, Texans rookie CB Lonnie Johnson Jr. — a second-round pick out of Kentucky — got sent off the field early for a hit he made on former Texas A&M TE Jace Sternberger.

Reports stated that the hit made Sternberger’s helmet come off, but added that it was a clean hit from all appearances:

After the practice, coach Bill O’Brien said he felt it was probably best to get Johnson off the field before things escalated:

Eventually, Johnson responded on Twitter, saying he isn’t trying to hurt anybody:

Sternberger also weighed in, saying there were no hard feelings between him and Johnson:

Practices between two teams are nice to break up the monotony of training camp, but sometimes they lead to scuffles like this.
