Lamar Jackson posted a perfect passer rating against the Cincinnati Bengals on Sunday, becoming just the second player in NFL history to produce a perfect rating in multiple games in a single season.
Ben Roethlisberger also did so with the Pittsburgh Steelers in 2007.
"I'm a quarterback at the end of the day," Jackson said. "I want to prove that each and every day I go out and practice. I treat it like it's a game. If I miss a pass at practice, I'm ticked off."
Jackson had a perfect rating in Week 1 against the Miami Dolphins. The Baltimore Ravens quarterback also had the longest touchdown run of his career in Sunday's 49-13 win over the Bengals.
