All-conference center Hroniss Grasu won't be suiting up when Oregon takes on Arizona in Friday's Pac-12 championship game, CSNNW's Aaron Fentress reports.

Grasu has been sidelined since suffering a leg injury Nov. 8 against Utah.

Running back Thomas Tyner will also be unavailable as he continues to nurse a shoulder and ankle injury. This will be his third consecutive missed game.
