Texas A&M gave up 384 yards rushing in a 23-17 loss on Friday night at Kyle Field.
Snyder has been at Texas A&M since coach Kevin Sumlin was hired at the school in 2012.
Sumlin says in a statement that Snyder: ''understands the production needed to be better on the defensive side of the football.''
The Aggies rank 103rd in total defense by allowing 449 yards a game. They allowed 223.5 yards rushing a game, which ranks 111th in the nation.
Linebackers coach Mark Hagan will be A&M's interim defensive coordinator for the team's bowl game.
