During the first of what will be two joint practices between the Packers and visiting Houston Texans in preparation for their exhibition meeting on Thursday, Sternberger was leveled by Texans cornerback Lonnie Johnson Jr. trying to catch a pass over the middle.
It was a crushing -- but clean -- hit that sent Sternberger's helmet flying.
Johnson stood over Sternberger's body, flexing; the cherry on top of the rookie-on-rookie crime -- and a gesture that wasn't too well received by either sideline. Texans head coach Bill O'Brien sent Johnson to the locker room for the remainder of practice, but not after a messy scuffle broke out between both teams.
