The iconic Oregon Duck has been unmasked.

Shortly before the season opener against Montana State on Saturday, Oregon’s mascot took a tumble during the pregame run onto the field, losing his head in the process.

After getting back up, the mascot sprinted to the tunnel headless in embarrassing fashion, with a staffer chasing after it with the head.

The mascot — who is informally named Puddles — was first debuted by Oregon in the 1940s, and has lost its head a number of times over the years, most recently during a standoff with Deion Sanders and Colorado back in 2023.

Before the game against the Buffaloes in September 2023 , the mascot arrived dressed like Sanders, sporting a white hat and sunglasses.
