The Oregon football rivalry with Oregon State is a bit more uncertain these days.
That's what happens when the Ducks fly away to the Big Ten and the Beavers get left behind in the major conference realignment.
But they'll match up on Saturday in non-conference action, and there's something big on the line: a platypus.
That's right: The rivalry trophy for this matchup is the Platypus Trophy.
It's not even recognized officially by the schools, instead just being exchanged between alumni associations. But it's awesome.
Why do Oregon and Oregon State play for the Platypus Trophy?
Really, this one is pretty simple: Take a duck, take a beaver, and mush them together.
A platypus has a duck-like bill and a beaver-like tail.
That was the inspiration in the late 1950s when the trophy was first created, according to ESPN.
The rivalry trophy, as many do, had its share of times being stolen, and its extended disappearance essentially led to its removal as an official trophy of the game.
By the time it showed back up, the Ducks and Beavers weren't bringing it onto the sideline to hoist off in victory. It's a more subtle, behind-the-scenes recognition.
It's still a platypus, though, and that's pretty awesome.
