Auburn added depth to its offensive line on Wednesday.

Former Jacksonville State offensive lineman Casey Dunn transferred to Auburn as a graduate transfer, the Tigers announced. The 6-foot-3, 285-pound Dunn, who was a two-time All-American for the Gamecocks, will be eligible immediately at Auburn.

Dunn will not be with the team when spring practices begin on Tuesday. Instead, he will arrive in the summer, an Auburn spokesman confirmed to AL.com.

Dunn, a product of Hewitt-Trussville High, started 27 games at center for Jacksonville State -- including the team's 27-20 overtime loss to Auburn at Jordan-Hare Stadium in 2015. In all, he appeared in 36 games for Jacksonville State, with five appearances as a freshman in 2013 and four appearances as a sophomore in 2014.

Dunn earned a spot on the Gamecocks' starting offensive line prior to his junior season and quickly became a fixture up front. In 2015, he earned AFCA All-America honors, and last season he was a second-team AP All-American.

While Dunn anchored Jacksonville State's offensive line, the Gamecocks ran for a school record 4,511 yards in 2015 -- the program's first 4,000-yard season on the ground. JSU also totaled 7,613 yards of offense that season, marking the school's first season of eclipsing 7,000 yards of total offense. That year, Jacksonville State also finished as national runner-up in FCS, losing to North Dakota State in the FCS championship game.

Last season, Dunn paved the way for an offense that rushed for 3,007 yards and 32 touchdowns, including 782 yards and seven scores from former Auburn running back Roc Thomas. JSU went 10-2 on the season and won the Ohio Valley Conference before bowing out in the second round of the FCS playoffs.

The addition of Dunn brings added experience to an Auburn offensive line that is replacing two starters this season following the graduation of left guard Alex Kozan and right tackle Robert Leff.
