For decades Frank Denius' presence around the Texas Longhorns' football program was ubiquitous.

The Texas-ex was known for constantly attending practices and games, and his name is emblazoned on the practice facility.

Just this past Sunday, Denius, a famed World War II veteran and lawyer, passed away in Austin at the age of 93. But the Longhorns still made sure that Denius was properly remembered when they opened preseason camp on Friday.

The team set up a portrait of Denius on the sidelines with flowers at its base.

Before practice began, Texas held a moment of silence and said a prayer to honor the life of Denius. Texas head coach Tom Herman even wore during practice a black T-shirt with the phrase "Cobra Strike" on it along with various military insignias, symbolizing Denius' participation in Operation Cobra Strike during World War II.

During Thursday's preseason camp press conference, Herman reflected on Denius' life and impact, calling him "an unbelievable man" and "an unbelievable Longhorn."

"I went along with Chris Del Conte and Greg Fenves, a week before he passed, went to his house and spent about an hour with him," Herman said. "He was not in great shape, but he had his T ring on. He could still give him 'Hook 'em, Horns.' We remembered how our kickoff team was named after him, the things he had done in the military and accomplished.

"I found out some unbelievable things about him. He was married for 64 years. Maybe the best story about him, I'll move on, but the best story about Frank that I heard was in 57 years, he had missed three home Texas football games -- 57 years. One of those was to receive the Congressional Medal of Honor, which at first he had declined to go. He said, 'I'm not missing a game for some silly honor.'"
