Junior cornerback Chris Seisay, one of Oregon's most experienced defensive players entering this season, has left the football program multiple sources tell DuckTerritory.com.

Seisay entered this summer's training camp in a position battle at cornerback with multiple underclassmen and has since fallen behind sophomore Ugo Amadi and redshirt freshman Malik Lovette.

"Right now, when he plays well, he's one of those guys (top 6 dbs), is he going to start, I don't know," defensive back coach John Neal said earlier this week.

"He just needs to be consistent, do what he can do."

Seisay wasn't at Oregon's practice on Saturday.

After redshirting in 2013, Seisay's career was on track to become a multi-year starter for the Ducks. He was the team's top cornerback off the bench in 2014 but assumed a starting role in the Rose Bowl and National Championship Game.

Entering 2014 Seisay was viewed as the team's top cornerback, but injuries kept him on the sidelines for eight of Oregon's 13 games. He finished the year with 22 total tackles.

Seisay played in 18 games in his first two seasons at Oregon and finished with 55 tackles, six passes defended, one interception, and a forced fumble.

The loss of Siesay will hurt Oregon's depth at the position this coming season, but Seisay wasn't expected to start this season.
