Oregon's longest-tenured assistant coach Gary Campbell's time at Oregon has come to an end.

Campbell tweeted Friday afternoon in two different tweets that he was not going to be coaching at Oregon next season after the athletic department fired Mark Helfrich and hired Willie Taggart.

Thanks to all for your kind words. Walked Oregon sidelines for over half my life.its been awesome but the walk has ended. God Bless you all. — Gary Campbell (@OregonRBCoach) December 23, 2016

Campbell was hired at Oregon in 1983 and has remained with the program ever since.

Campbell had considered retiring following the season he confirmed to the Oregonian earlier in the year.

"I think about it. I don't know when I'll do it, but it's close," Campbell said in a November interview with the Oregonian.

Under Campbell's coaching, the top nine career rushers in Oregon program history played for Campbell, including this year's running back Royce Freeman.

This year ended a nine-year streak where the Ducks had a 1,000-yard rusher, which at the time was the longest active streak in the FBS level.

Campbell's departure is the third known assistant coach under Helfrich who will not be back. Oregon defensive coordinator Brady Hoke was replaced by Jim Leavitt and Oregon offensive coordinator Matt Lubick has taken a position at Ole Miss coaching wide receivers.
