Johnson was selected with the Indianapolis Colts' sixth-round pick in the 2006 NFL draft.[1] As a rookie, he started one game, filling in for the injured right tackle Ryan Diem against Tennessee in week 13, and, additionally, filled in for Diem for a portion of Super Bowl XLI.
Due to the retirement of stalwart LT Tarik Glenn, Johnson had an opportunity to win the starting left tackle job during his second season, but was beaten out by rookie Tony Ugoh. Injuries to Ugoh and Diem, however, led to Johnson starting 10 of 16 games at LT and RT, respectively. Johnson's performance during the 2007 was widely viewed by fans as a disappointment (that season marked the first time in five years that the Colts finished out of the top 5 in least sacks allowed), considering the competence he had shown as a rookie.
In Johnson's third season, he was moved to left guard in order to compensate for the loss of injured starter Ryan Lilja. Johnson started all 16 games, 12 at LG and 4 at LT, and was one of only two starting OL (the other being Ryan Diem) to play in every game that season.
The following year, Johnson beat out underachieving starter Tony Ugoh for the starting LT position during training camp. Through six games, Johnson had demonstrated solid improvement at his position, in contrast to previous years' performances.
