Pac-12 officials coordinator resigns

In the wake of a tumultuous couple of weeks for Pac-12 officials, the league's coordinator of football officiating has resigned.

The Pac-12 announced Tony Corrente's resignation in a statement Wednesday night, citing personal and professional reasons.

"Under Tony's leadership, our program made great strides in improving the quality, accountability and consistency," commissioner Larry Scott said in the statement. "While it's unfortunate that Tony has decided to leave us at this time, I want to express my appreciation for his contribution, and for leaving our officiating program strong and headed in the right direction."

Pac-12 officials have come under fire the past couple of weeks following a series of high-profile, questionable calls and non-calls in several games. It spilled over Saturday in Colorado when coach Mike MacIntyre was seen screaming at officials and following them off the field following the Buffs' 36-31 loss to Oregon State. The tirade earned MacIntyre a $10,000 fine and a reprimand from the league earlier this week.

Corrente had served as the Pac-12's officiating coordinator since 2011 and is an NFL official who worked last season's AFC Championship Game. He missed part of the 2012 season after being diagnosed with throat cancer.

Jim Blackwood, who has more than 20 years as a college conference coordinator and 10 years as an NFL replay official, will serve as interim coordinator for the remainder of the season. He previously served as the instant replay supervisor under Corrente.

The league will conduct a search for a permanent replacement after the season.
