EUGENE, Ore. — Quarterback Marcus Mariota has announced that he will return to Oregon for his junior season.

There had been speculation that Mariota might declare himself eligible for the NFL. But on Tuesday the school announced on its website that Mariota would stay, along with junior Hroniss Grasu, a three-year starter at center.

“It is an honor to be a student at the University of Oregon and to have the opportunity to represent our institution on the football field alongside my teammates,” said Mariota, who has thrown 30 touchdowns this season. “I look forward to earning my degree next year and to the rest of my career at this great University.”

Meanwhile, the Bowl Championship Series announced Tuesday the 20 football teams still under consideration for BCS berths, and, not surprisingly, it includes 10-2 Oregon.

That means the Pac-12 bowl picture — which includes Arizona — will likely remain in flux until announcements are made Sunday.

If the BCS had released Oregon, it could have set in motion a process by which the bowls in the Pac-12 pecking order could begin to commit to programs, or at least develop either/or scenarios.
