FRISCO -- The Cowboys' dinosaur showed Tuesday he isn't extinct just yet.
Cowboys defensive lineman David Irving, whom defensive coordinator Rod Marinelli affectionately calls Dino because of his 6-7 height and long arms, returned to the practice field for the start of the club's three-day mandatory minicamp.
Irving, however, didn't do much on the field. He went through pre-practice stretching before heading to the sideline for some running. He didn't participate in any individual or team drills.
He appeared ready to open up on his tumultuous offseason in front of his locker Tuesday with media surrounding him. But just before he fielded questions, fellow defensive lineman DeMarcus Lawrence yelled at him that he could just talk Wednesday.
Irving followed with a quick statement before adding that he'd talk more Wednesday about what's kept him from practicing the last three weeks during voluntary organized team activities.
