Vikings coach Leslie Frazier has started to make some changes among his assistants, but the moves do not include a shakeup at offensive coordinator.

As of now, Darrell Bevell remains in that position and there appears a possibility he could stay in the role.

Quarterbacks coach Kevin Rogers has been let go and offensive line coach Pat Morris and assistant offensive line coach Jim Hueber also have been relieved of their duties.

Frazier, who had the interim label removed from his title on Monday, has been meeting with the assistants in recent days. It's not certain if Frazier is planning to make any further moves. Special teams coordinator Brian Murphy remains on staff but he appears to be in the same boat as Bevell. That means that both are safe for now but there is no clear indication if that will remain the case.

Frazier needs to hire a full-time defensive coordinator but it's expected Fred Pagac will be promoted to that job. Pagac, the Vikings linebackers coach, was the interim coordinator after Frazier was moved from defensive coordinator to interim coach in late November.

Frazier would need to hire a linebackers coach to replace Pagac but that job could go to his friend and former 49ers coach Mike Singletary, who also could get an assistant head coaching title. The Vikings also need a running backs coach to replace Eric Bieniemy, who will be offensive coordinator at Colorado. That job could go to longtime NFL assistant and former player Johnny Roland, whom Frazier knows from their days together in Chicago.
