Mississippi State has promoted Chris Wilson to defensive coordinator, one day after Manny Diaz left the position to take the same job at Texas.

The 41-year-old Wilson joined Mississippi State last season as co-defensive coordinator and defensive line coach. Before coming to Starkville, he spent five seasons as an assistant at Oklahoma, including the last three as special teams coordinator.

Mississippi State's defense ranked third in the Southeastern Conference this season, giving up 19.9 points per game. The Bulldogs finished with a 9-4 record, beating Michigan 52-14 in the Gator Bowl on Jan. 1.

MSU also announced that Angelo Mirando has been promoted to receivers coach after serving the past two seasons as a graduate assistant.
