The Cleveland Browns have confirmed the departure of offensive coordinator Kyle Shanahan and quarterbacks coach Dowell Loggains after just one season at the club.

The 35-year-old helped keep the Browns competitive in their matches this season despite being without All-Pro wide receiver Josh Gordon for 10 games, while quarterbacks Brian Hoyer and Johnny Manziel struggled in their time on the pitch.

Reports suggested that Shanahan was unhappy with the switch from Hoyer to Manziel at the end of the season and that has resulted in his departure from the club.

"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," head coach Mike Pettine told the club's official website.

"In Dowell's case, it was a difficult decision but one that we felt we had to make. We wish them both well. Our focus quickly turns to finding an outstanding coach to lead our offense and I am confident we will bring in highly qualified individuals to help us develop, improve, and achieve the success we are all seeking.

"I look forward to working with the staff as we go through this process to bring in coaches committed to helping the Cleveland Browns lay a strong foundation to take our offense to a consistently high level in the 2015 season and beyond."

Shanahan has been linked with the head-coaching vacancy at the Buffalo Bills, along with other offensive coordinator positions.
