CINCINNATI — Coach Marvin Lewis warned Bengals players that more changes are coming if they continue to lose, and the next job lost could be theirs.

The Bengals fired offensive coordinator Ken Zampese a day after their 13-9 loss to the Texans on Thursday night. Quarterbacks coach Bill Lazor was promoted and will get his first chance to put his imprint on the offense for a game Sunday at Green Bay (1-1).

Lewis said his message to the team this week is that it’s on them now to fix the problems.

“I told the players on Monday morning: This is not magic,” Lewis said Wednesday, the first time he’s been available to the media since the change. “You have to do the work — offense, defense and special teams all alike. We all got Kenny out of here — not Kenny, we did.

“And they’ve got to understand that. They’re part of that. And the next time they look around, there will be different guys sitting there.”

The Bengals (0-2) are the first team since the 1939 Eagles to open a season with a pair of home games and fail to score a touchdown.
