News came down on Tuesday afternoon that had been expected for quite some time in Eugene.Oregon Ducks defensive coordinator Tosh Lupoi is moving on from Eugene and beginning his head coaching career. It’s the California Golden Bears who are hiring Lupoi after parting ways with long-time head coach Justin Wilcox earlier this month. Lupoi, a California alum, was among the top candidates for the job, and the two sides moved quickly in getting a deal done.Lupoi was one of the first hires for Lanning when he took over as the head coach in Eugene, and he has progressively improved as the defensive play-caller for the Ducks. Oregon has one of the best defenses in the nation this year, ranking No. 8 in scoring defense (15.0 ppg), and No. 2 in total defense (252.3 ypg). While it’s a bummer to see Lupoi leave Oregon, many fans were happy that he gets this opportunity to take over his own team. Here’s how fans reacted on social media on Monday afternoon:Just Part of the GameMan why is it so hard to be an elite program some times 🦆Best of luck to Will Stein and Tosh Lupoi. You helped make Oregon the best program in the nation. We’ll miss you.— Lucy (@hilucyleduck) December 2, 2025Everything is Fine!https://t.co/DUYta97uXppic.twitter.com/0PGTIdvht6— Barstool Ducks (@BarstoolDucks) December 2, 2025Busy Offseason Coming!Oregon lost both coordinators in 24 hours 😳 https://t.co/jNhTn66Pz6— SleeperCFB (@SleeperCFB) December 2, 2025The Plan is in PlaceNo surprise here. Tosh will bring juice to Cal they haven’t had in awhile. I assume Hampton will get full time DC duties even tho I suspect he’s been calling some of the defense. It’s still Lanning’s defense in the end. https://t.co/C3sguUyJ42— Geoff Schwartz (@geoffschwartz) December 2, 2025Big Shoes to Fillhttps://t.co/p2pVUDt13Ipic.twitter.com/cSU0jYbCy8— H𝐎mer (@OregonHomer) December 2, 2025Chris Hampton Time!If Cal finalizes the deal to hire Tosh Lupoi, Oregon is expected to name Chris Hampton as its new defensive coordinator, sources tell @CBSSports.Hampton has worked at Oregon the last three years as co-defensive coordinator. Before that, he was defensive coordinator at Tulane. pic.twitter.com/utdZK4d2Ta— Matt Zenitz (@mzenitz) December 2, 2025HUGEBANGGGGG #GoDuckshttps://t.co/67ssWXRcNx— Geaux Ducks (@GeauxDuck) December 2, 2025Cyrus Knew✅ https://t.co/7vvy792Blk— Cyrus Smith (@CoolCyWrites) December 2, 2025One Last DanceOregon’s season currently pic.twitter.com/Xe12V7KcH4— 🦆 B1G Duck Energy 🦆 (@B1GDuckEnergyy) December 2, 2025CFP PlanI’m told that the current expectation is for Tosh Lupoi to stay on and coach Oregon throughout the College Football Playoff, much like Will Stein plans to do. https://t.co/h8YiZkO8i3— Zachary Neel (@zacharycneel) December 2, 2025That Coaching Tree Is FlourishingThe Lanning Coaching Tree is growing rapidly pic.twitter.com/iM8WpAO0bq— Barstool Ducks (@BarstoolDucks) December 2, 2025Have Fun With JKShttps://t.co/H6xAus7YcWpic.twitter.com/W9CvFRWCp0— The Bear Necessities (@justthebears) November 24, 2025Contact/Follow @Ducks_Wire on X (formerly Twitter) and like our page on Facebook to follow ongoing coverage of Oregon Ducks news, notes, and opinions.This article originally appeared on Ducks Wire: Oregon Duck fans react on social media to Tosh Lupoi’s departure
