Indianapolis Colts head coach Frank Reich has made another major change to the teams' offense by relieving offensive coordinator Marcus Brady of his duties.

The latest shakeup comes around one week after veteran quarterback Matt Ryan was benched and replaced by second-year player Sam Ehlinger.

"This was an incredibly hard decision, but one I felt needed to be made in the best interest of the team," head coach Frank Reich said in a statement. "I appreciate Marcus' commitment to the organization, and he made a significant contribution to our offensive success over the last five seasons. I wish him the best moving forward."
