AIR FORCE ACADEMY, Colo. (AP) -- Air Force football coach Troy Calhoun has added new assistants Ron Vanderlinden and Tim Cross to his staff.
Titles and coaching assignments haven't been determined.
Vanderlinden joins the Falcons after 13 years at Penn State, where he coached linebackers, and Cross joins Air Force after spending the last three years as strength and conditioning coach at Texas. Before that, he was associate head coach at Minnesota, where he was in charge of the defensive line.
Cross attended Gateway High School in Aurora, Colo., and is a 1990 graduate of Northern Colorado, where he was a four-year letterman in football.
