Gruden is the younger brother of Jon Gruden who was the head coach at Tampa Bay and Oakland and is currently a television commentator. Jay Gruden is replacing Bob Bratkowski, who was fired this week after 10 seasons with the Bengals.
Jay Gruden coached the UFL's Florida Tuskers last year and was moving to the league's franchise in Virginia when the Cincinnati opportunity came up. He previously was on Jon Gruden's staff at Tampa Bay.
"We are excited to have Jay join us and give us a new direction offensively," said Bengals Coach Marvin Lewis in a news release. "He has proven himself a consistent winner in a variety of positions and has earned tremendous respect in the coaching profession. He's going to provide the energy and attacking style that will best suit our offensive skill players and quarterback."
