Mario Cristobal plans to continue coaching Oregon’s offensive line.

But the program’s first-year head coach is going to have some help from an old friend.

Cristobal will complete his staff by hiring Alex Mirabal, who also coached for him at Florida International, to coach centers and offensive guards.

The Huntington (W.Va.) Herald-Dispatch was the first to report Mirabal as Cristobal’s 10th and final hire, which a source confirmed to The Register-Guard.

Cody Woodiel, a graduate assistant who spent the past three seasons as the offensive line coach at Itawamba (Miss.) Community College, will coach the Ducks’ offensive tackles.

“I’m an offensive line coach by trade,” Cristobal said after adding five offensive linemen to the roster on national signing day. “What we see every single year, games are won and lost at the line of scrimmage. They are. And our offensive lines and defensive lines have done one heck of a job in year one. …

“We’re going heavily in on the offensive and defensive lines because it makes everything else go.”

Mirabal spent the last five years at Marshall. The Thundering Herd finished fourth nationally last season in sacks allowed, giving up 11 in 13 games.

Cristobal has known Mirabal since their freshman year at Miami’s Christopher Columbus High.

Oregon’s full-time staff for the 2018 season includes five holdovers from the brief Willie Taggart era — defensive coordinator Jim Leavitt, offensive coordinator Marcus Arroyo, defensive line coach Joe Salave’a, safeties coach Keith Heyward and wide receivers coach Michael Johnson.

Since being elevated to head coach on Dec. 8, Cristobal also added assistants Cort Dennison (outside linebackers), Jim Mastro (running backs), Bobby Williams (special teams) and Donte Williams (cornerbacks).
