Ames, Iowa Iowa State coach Paul Rhoads says offensive coordinator Mark Mangino has left the program.
Rhoads says he and Mangino haven't been on the same page for weeks. Rhoads wouldn't say whether Mangino quit or was fired.
The move Monday came on the same day Iowa State promoted sophomore Joel Lanning to a starting role over senior Sam Richardson, but Rhoads says Lanning's promotion was not the reason Mangino left.
Rhoads announced that passing game coordinator Todd Sturdy will take over for Mangino, starting with Saturday's game against Texas (3-4, 2-2 Big 12).
Mangino was 50-48 in eight seasons as the coach at Kansas. He joined Rhoads' staff prior to last season.
Iowa State (2-5, 1-3) is averaging 26.9 points per game.
