The No. 14 Oregon Ducks (10-3) return to the field on December 29th against No. 16 Oklahoma (10-2), but they’ll look drastically different from the last iteration of the UO team that saw the field in the Pac-12 Championship Game.

That Oregon team lost to No. 11 Utah for the second time in three weeks to the Utes. But in the last three weeks, head coach Mario Cristobal has left the team to become the head coach of Miami, offensive coordinator Joe Moorhead left to take the head coaching job at Akron, linebacker coach Ken Wilson left to take the head coaching job at Nevada, and defensive coordinator Tim DeRuyter left to take the same position at Texas Tech.

In addition, the Ducks lost key players to the NFL Draft—like edge rusher Kayvon Thibodeaux—in announcements that revealed they’ll also sit out the bowl game. Wideout Devon Williams and corner Mykael Wright have also declared. DJ James and Jayson Jones have also entered the transfer portal.

The Ducks released a depth chart Tuesday for the upcoming bowl game, and there are quite a few changes to sort through.
