Oregon added a fourth graduate transfer for next season when Alabama offensive lineman Dallas Warmack elected to reunite with Mario Cristobal on Saturday.

The 6-foot-2, 308 pounder committed to the Ducks during a weekend visit on campus.

"I am going to play my last two years for the coach that I believe in most," Warmack posted on Twitter. "Coach Cristobal let's take Oregon to the highest level!"

Cristobal recruited Warmack to Alabama when he was the offensive line coach for the Crimson Tide. He was the position coach when Warmack played seven games at guard for Alabama as a true freshman in 2016.

Warmack played nine games as a sophomore but did not take the field last season, leaving him two years to play for the Ducks.

Warmack was a four-star recruit out of Atlanta who played in the U.S. Army All-American Game. He picked the Crimson Tide over offers from Auburn, Florida State, and Texas.

His brother, Chance, was a first-round pick of the Titans in 2013 who won a Super Bowl last year as a guard for the Philadelphia Eagles.

Oregon returns guard Shane Lemieux at guard while sophomore Jacob Capra was listed as the starter at right guard entering spring drills. The Ducks do not have much experience behind those two with sophomore Sam Poutasi and junior Charlie Landgraf listed as the back-ups.

Cristobal continues to add veterans who are eligible next season with Warmack joining wide receiver Tabari Hines of Wake Forest, cornerback Tim Hough of UNLV, and tight end Kano Dillon of South Florida as grad transfers who will join the Ducks in the fall.
