2014 Heisman Trophy winner Marcus Mariota may be in Tennessee, but the Ducks will still have a Mariota in uniform come Sept. 5.
Marcus' younger brother Matt, an outside linebacker, has officially joined the Ducks as a walk-on. He is one of seven new walk-ons to be added to Oregon's 2015 roster.
The Ducks opened fall camp on Monday and will open their season on Sept. 5 vs. Eastern Washington.
