In 1910, the University of Texas asked Yost to recommend a coach for the Texas varsity football team, and Wasmund was hired on Yost's recommendation. Wasmund led the Longhorns to a 6–2 record in 1910, and he was rehired to return as head coach in 1911. On October 1, 1911, six days before the opening game of the 1911 season, Wasmund fell from the second-story window of the apartment where he was living near the University of Texas campus. Wasmund was rendered unconscious by the fall and received bruises to his hands, arms and hips, a deep gash on the forehead and deep cuts on both legs. He regained consciousness Sunday afternoon, but died three days after his fall. Wasmund was known to be a somnambulist, and it is thought that he walked through the window while sleep-walking. Death resulted from a rupture of the bladder and peritonitis. Wasmund was 23 years old at the time of his death.
