Jaguars quarterback Blake Bortles telegraphed a pass toward the sideline, and Texans cornerback Kareem Jackson was waiting.
Joseph kept his balance and stayed inbounds, and he returned the interception 42 yards for a score.
It was a bad decision by Bortles, and the ball floated. Once Jackson grabbed it and got his feet under him, he only had to make one cut to avoid being tackled. The Texans are up 7-0 before running an offensive play.
