College Station, Texas ? Texas A&M defensive coordinator Gary Darnell was named interim head coach Saturday, a day after Dennis Franchione resigned. Darnell, 59, joined Franchione’s staff in 2006 after serving eight seasons as head coach at Western Michigan. He had been out of coaching a year when Franchione hired him. Franchione stepped down after the Aggies defeated Texas 38-30 at Kyle Field on Friday. A&M (7-5, 4-4 Big 12) went 32-28 in Franchione’s five seasons.
