Iowa State coach Paul Rhoads announced Monday he has dismissed offensive coordinator Mark Mangino, citing that the two "couldn't get on the same page on a few important items."
"We tried to talk that through again this morning in an effort to get us moving in a different direction," Rhoads said during a news conference. "In the end, Mark was not interested in that. I wish that wasn't the case, but I respect and understand his conviction."
Passing game coordinator Todd Sturdy will take over play-calling duties for the Cyclones.
Some Iowa State players, whom Rhoads hadn't informed before announcing the change, seemed to show their surprise at the move on Twitter.

The Cyclones had a team meeting Monday to discuss Mangino's dismissal.
"Being the head football coach requires you to be a leader, and you're the CEO," Iowa State athletic director Jamie Pollard told The Associated Press on Monday. "Most people think it's about X's and O's. But it's about leading a really big organization. So with that comes tough decisions."
After returning to coaching in the FBS after a four-year absence, Mangino lasted just seven games into his second season as offensive coordinator for the Cyclones.
As a head coach, Mangino led Kansas to a 12-1 record in 2007, which included a victory in the Orange Bowl, before resigning two years later amid allegations of player mistreatment. Before that, he was the offensive coordinator on Oklahoma's national championship team in 2000.
A source told ESPN's Adam Rittenberg that the differences between Rhoads and Mangino had been building for some time over play selection and personnel usage, and that the parting wasn't related to a single or isolated incident.
"We couldn't get there," Rhoads said. "In the end, there was no compromise but to move on."
Mark Mangino's son, Tommy Mangino, will remain on staff as the team's wide receivers coach, Rhoads said.
Rhoads also announced Monday that Joel Lanning would replace Sam B. Richardson as the Cyclones' starting quarterback. Lanning completed 12 of 17 passes for 144 yards and three touchdowns Saturday in the 45-27 loss at Baylor.
Iowa State (2-5, 1-3 Big 12) hosts Texas this weekend.
