Oklahoma State head coach Mike Gundy now has two staff positions to fill. Less than a week after parting ways with offensive line coach Greg Adkins, running backs coach Marcus Arroyo has left to become an offensive assistant at Oregon.

Arroyo joined the OSU coaching staff in 2015 and almost immediately paid dividends. Freshman Justice Hill rushed for over 1,100 yards last season and the Cowboys had just landed 4-star running back Chuba Hubbard in their 2017 class. A highly coveted back out of Alberta, Canada, Hubbard turned down the likes of Auburn, Oklahoma, Oregon, Tennessee and others to come to Oklahoma State.

Having spent his college days at San Jose State (where he also got his coaching start), Arroyo is returning to the West Coast. According to ESPN’s Jake Trotter, Arroyo will be the co-offensive coordinator (in charge of the passing game) and quarterbacks coach.

Sources are also reporting that Mike Gundy is close to hiring Josh Henson as the Cowboys’ new offensive line coach.
