Ranked last in total points scored, yards per game and passing yards, the hope is Shoop gives the offense a boost. Oakland has averaged just 12 points per contest through the first 11 games and only have two second half touchdowns.
"In this business, at times there are tough decisions that have to be made for the good of the football team," head coach Art Shell said.
Shoop, 37, has been with Oakland for the last two seasons, serving as their quarterbacks coach in 2005.
The offense was clearly not on par with the way the defense had been performing, prompting San Diego quarterback Philip Rivers to note, "If they could have put up 21 or 28 points week to week they would be right there in the hunt for this division."
