He played in the Wisconsin Shrine Game. As a senior, he won the state title in the shot put and was named the conference player of the year in basketball. College career Johnson accepted a football scholarship from the University of Wisconsin–Madison along with his cousin Ben Johnson. As a redshirt freshman, he appeared in 7 games, playing mainly on the field goal and extra point conversion lines. He became a starter at center in the second game of his sophomore season, when All-American Casey Rabach was moved to right guard. He started every game as a junior. He was named team captain and received second-team All-Big Ten honors as a senior. Professional career Dallas Cowboys One of the priorities in Bill Parcells first season as the head coach of the Dallas Cowboys was improving the center position play. To that end, he made Andre Gurode concentrate on playing guard and selected Johnson in the second round (38th overall) of the 2003 NFL Draft. In training camp he was named the starter, but suffered a right knee injury during a practice that required microfracture surgery, which was thought to be career-threatening, because at the time not many players fully recovered from this medical procedure. In 2004, Tyson Walter was named the starter at center, but suffered a sprained left knee in the second quarter of the season opener against the Minnesota Vikings, opening the door for Johnson to start in the rest of the games. The next year, after facing competition in training camp from Gurode, he went on to start all 16 games, but still split time at center. In 2006, he lost the starting position to Gurode, who went on to become a Pro Bowler. The Cowboys didn't re-sign him in free agency at the end of the season.
