Berea, OH (SportsNetwork.com) - The Cleveland Browns announced the resignation of offensive coordinator Kyle Shanahan on Saturday and also parted ways with quarterbacks coach Dowell Loggains.

Reports circulated earlier this week that Shanahan wanted to leave after just one year on the job because of problems with the front office.

According to the Cleveland Plain Dealer, the Johnny Manziel issue was not the prominent reason for Shanahan's decision. The paper said other personnel matters with general manager Ray Farmer played a major role.

"After conversations with Kyle this week we've determined that it would be in the best interest of the Cleveland Browns that he pursue other opportunities and we have accepted his resignation." said Browns head coach Mike Pettine on Saturday. "In Dowell's case, it was a difficult decision but one that we felt we had to make. We wish them both well."

Shanahan still had two years left on his contract with Cleveland. He joined the Browns last February after spending four years as offensive coordinator with the Washington Redskins under his father, Mike.

In addition, the younger Shanahan was the offensive coordinator with the Houston Texans.

"I appreciate the opportunity Mike Pettine, Ray Farmer and (owner) Jimmy Haslam gave me to lead the Browns offense in 2014," said Shanahan. "The Browns organization is committed to improvement and winning. I regret how the inner workings of the organization were represented publicly over the last few days. Ray and Mike both have the work ethic, experience and talent to work together to turn this organization into a winner. In light of the circumstances, I have decided to resign. I'm grateful for my time with the Browns and wish them great success going forward."

The Browns were in the thick of the playoff race after a 7-4 start, but lost their last five games to finish last in the AFC North at 7-9.

A quarterback controversy with Manziel, one of Cleveland's two first-round draft picks last May, and Brian Hoyer developed late in the season. Hoyer had started the first 13 games before Manziel was given the nod.

Manziel struggled badly in his first start, a 30-0 loss to Cincinnati that essentially ended Cleveland's slim playoff hopes in Week 15.

Loggains joined the Browns last February after eight years with Tennessee, serving as the Titans' offensive coordinator in 2012-13.
