Oregon State defensive tackle Stephen Paea, the 2009 Morris Trophy winner as the Pac-10's best defensive lineman, will return for his senior season, according to an athletic department spokesperson.
Paea joins Washington quarterback Jake Locker as the conference's top two underclass NFL prospects who opted to return for their senior seasons.
Arizona is still awaiting final word from junior tight end Rob Gronkowski, but he's expected to enter the draft if he's medically cleared to participate in the NFL combine. Arizona will hold a press conference for Gronkowski at 1 p.m. (EST) on Friday.
The deadline for underclassmen to declare for the draft is Friday.
